A system for monitoring carbon monoxide (CO) levels produced by the operation of a vehicle's engine. The system includes a detector in the vehicle's passenger compartment for detecting the concentration of CO inside the compartment and circuitry for generating a HIGH CO signal when the detected concentration of CO inside the compartment is greater than a predetermined level. The system disables the operation of the engine in response to the HIGH CO signal. The system also senses a status condition of the vehicle and inhibits the disabling of the engine when the status condition is sensed.

A case sealed by a strip of pressure-sensitive tape having an integral end portion of the tape at an end thereof folded back on the adhesive face of the tape and adhered thereto to form a tab which is unadhered to the case for being grasped and pulled to peel the tape away from the case, and a method of and apparatus for taping cases with this easy-open feature.

Easy-open case taping method and apparatus

An escapement system in which units are movable by and with an endless conveyor in an endless path, and an escapement system is provided for retarding the units as they move through a part of their path, then releasing them; the system being incorporated in packaging apparatus in which the endless conveyor is a wheel and the units are sealing dies on the wheel.

Escapement system particularly for packaging apparatus

A method of opening a folded web of flexible heat-sealable packaging material prior to formation of the material into sealed reclosable packages. The web has a pair of interlockable reclosable closure strips extending longitudinally of the web on an inside face of the web, and one section of the web is folded over on another section of the web so that the closure strips are interlocked. The method comprises advancing the folded web in a first plane to a web-opening station, and opening the folded web while maintaining the closure strips interlocked as the web advances through the web-opening station. The web is opened by diverting both sections of the web relative to one another so that they assume a co-planar position in a second plane different from the first plane.

Method of and apparatus for opening a folded web of heat-sealable

Method of and apparatus for forming filling and sealing packages in which flexible packaging material is formed into tubing, the tubing is fed downwardly and transversely heat sealed at package length intervals by closing a pair of sealing members, the seal area is cut to form a top seal of the package being completed and a bottom seal for the next package to be formed, a quantity of product with which the packages are to be filled is delivered into the lower end of the tubing to provide a fill for each package, the tubing is pinched closed, after the delivery of each fill, above and below the level of the next seal to be made, the pinches are maintained as the sealing members are opened, following the formation of the aforementioned top and bottom seals, to keep product for the next fill from dropping down on the bottom seal, and to hold the package being completed from dropping away, and air is blown on the top and bottom seals to cool them while the pinches are maintained. The movement of the upper and lower pinch members between their open and closed positions are independent of the movement of the sealing members between their open and close positions so that the timing of the opening and closing of the pinch members relative to the opening and closing of the sealing members may be varied.

Method of and apparatus for forming filling and sealing packages

A carton loading machine comprising an endless conveyor carrying a series of holders each adapted to hold an erected carton in upright position and movable to move each holder from a carton receiving station for entry of an erected carton in the holder from the outside of the conveyor to a loading station for loading the carton and thence to a discharage station for discharge of the loaded carton, each holder having a fixed side and a movable side and latch members associated with said sides, the latch member associated with the fixed side and the movable side and latch member associated therewith being movable between open and closed positions.

Method of and apparatus for forming, filling and sealing packages wherein a web of flexible packaging interval is formed into tubing around a mandrel and intermittently fed downwardly in package length increments by intermittently moving portions of continuously driven belts into engagement with the tubing for a predetermined interval.

Vertical form-fill-seal method and apparatus

Easy-open case taping

A package comprising a wrapper formed from a single web of flexible sheet material formed into a tube having overlapping edge margins sealed together to form a single longitudinal seam for the tube lying substantially in the plane of one wall of the package, and a pair of end seals at opposite ends of the package, at least one end seal comprising end portions of two opposite walls of the tube sealed together in face-to-face relation in a plane extending longitudinally of the tube and generally at right angles to the plane of the overlapping edge margins forming the longitudinal seam.

Package of enwrapped articles

A pack or bundle comprising a bag of thermoplastic film such as polyethylene, individual packages of rolls of paper, such as packages of four rolls of toilet tissue, packed in the bag, a closure panel inserted in the bag engaging the contents, the panel being heat-sealable on its outside face, the bag having a marginal lip at its mouth projecting beyond the closure panel folded over on the outside face of the closure panel and heat-sealed thereto to close the bag, and the method of making such bundles involving inserting the contents and the closure into the bag through its mouth, and folding over the lip and heat-sealing it to the panel.

Packing articles, such as packages of rolls of paper

A method of and apparatus for wrapping units to be wrapped, such as two rolls of paper, in which transverse lines of weakness are formed in a web of flexible sheet wrapping material at measured intervals along the length of the web corresponding to wrapper length as the web is continuously fed forward, the web is formed into a tube around the units with the lines of weakness extending girthwise of the tube and spaced lengthwise of the tube at the wrapper length intervals, the units are fed into the tube one after another spaced lengthwise in the tube at wrapper length intervals and located between the lines of weakness, the tube with the units therein is continuously fed forward at a predetermined speed, and the leading wrapper of the tube with a unit therein is pulled forward at higher speed to sever it from the tube at the line of weakness between it and the preceding wrapper.

Method of and apparatus for wrapping articles

A form-fill-seal packaging method and apparatus in which a web of flexible packaging material is pulled from a supply and fed over a device for forming it into tubing, product to be packaged is provided in the tubing, and the tubing is sealed to form packages, and in which the web is pulled forward from the supply as one operation and the tubing is drawn forward and thereby taken up as an accompanying but separate operation with the take-up such that the web is pulled over the forming device under tension.

Form-fill-seal packaging method and apparatus

Method of and apparatus for wrapping reams of paper or the like in which the ream being wrapped is placed on an elevator mechanism at a lower level and raised by the elevator mechanism to an upper level. The elevator mechanism comprises a central support and two outboard supports extending endwise of the ream. The outboard supports are movable inwardly from an outer position wherein they are spaced outwardly from the central support. The outboard supports occupy their outer position as the ream is placed on the supports and while the ream is being raised. As the ream is raised, it engages a wrapper sheet and portions of the wrapper sheet fold down on the sides of the ream. When the ream is raised, underfolders move in under the ream from opposite sides of the ream to fold portions of the sheet in under the bottom of the ream. The outboard supports move inwardly toward the central support to clear the way for the underfolders to move in, and are then returned to the lower level and moved out to their outboard position. The central support is moved down to the lower level and the underfolders move into the region vacated by the central support. The ream is then pushed off the underfolders and the latter are retracted. As the ream is pushed forward, the ends of the wrapper sheet are tucked in on the ends of the ream by moving a pair of rearward tuckers forward from a retracted position and by moving the ream past a pair of fixed forward tuckers. The rearward tuckers are moved outwardly away from the ends of the ream as they return to retracted position to a position clear of the next ream being raised.

Method of and apparatus for wrapping

Method of and apparatus for squaring reams of paper as they are fed toward a wrapper, the squaring up being accomplished as the reams are moving forward toward the wrapper.
