A system for securing the unaffixed tail of a roll product to a convolution thereof underlying the tail with a flexible sealing element wherein a predetermined physical characteristic of the roll product is sensed and an appropriate sealing element such as a label is delivered to the roll product and applied thereto.

Roll product tail securing system

A shrink tunnel, a gate for opening and closing the egress opening of the shrink tunnel, prime mover means for moving the gate, and sensing means operatively connected to the prime mover means to open the gate just prior to exit of an article from the shrink tunnel and to close the gate after the product has exited therefrom.

Shrink tunnel with movable gate

Apparatus for securing plastic film about a product including a curved forming plate, sealer means cooperating with the plate to form spaced discrete heat seals in overlapping portions of plastic sheet disposed about the plate and product, and transport means for reciprocatably moving the sealer means so that it remains in engagement with overlapped sheet portions and follows the path of movement thereof for a predetermined period of time.

Plastic film wrapper and sealer apparatus

Apparatus for culling cant ends from a cant including a first conveyor upon which the cant ends are formed and a second conveyor which forms a gap with the first conveyor when the cant ends are positioned for transfer therebetween so that the cant ends will fall through the gap.

Apparatus for culling cant ends

A system for transporting discrete articles such as paper roll products in a predetermined number of flow lines and consolidating the articles into a lesser number of flow lines.

Discrete article transport and consolidating system

Apparatus for applying labels, coupons or the like to articles transported serially along a predetermined path of movement comprising storage means for the labels, delivery means for removing individual labels from the storage means and bringing the labels into contact with the articles, and applicator means for positively engaging the labels to hold them on the articles after delivery.

Apparatus for applying labels or the like

In a cabinet for manually dispensing sheet material from a roll rotatably mounted within the housing of the cabinet, a combination of a blade having a cutting edge and movable from a first position to a second position relative to the housing when the sheet material is manually pulled against the cutting edge to sever a portion of the sheet material from the remainder of the roll, and sheet delivery means in operative association with the remainder of the sheet material and responsive to movement of the blade from the first position to the second position to deliver the free end of the remainder of the sheet material to a position facilitating manual grasping thereof by the user.

Sheet material dispensing device

A dispensing device for sequentially dispensing sheet material such as paper toweling from a primary roll and a reserve roll, the primary roll initially being rotatably mounted at a first location and adapted to be displaced therefrom to a second location. Sheet material feed means is provided for dispensing the sheet material from the device. Sensing means is provided for sensing displacement of the primary roll from the first location and transfer means is employed in operative association with the sensing means and responsive to the sensing of the displacement of the primary roll from the first location to place sheet material from the reserve roll into operative engagement with the sheet material feed means. The transfer means includes metering means for metering sheet material removed from the primary roll by the feed means after displacement thereof has been sensed by the sensing means, said transfer means being responsive to the metering of a length of sheet material having been removed from the primary roll before placing the sheet material from the reserve roll into operative communication with the sheet material feed means.

Method of and apparatus for securing the tail or outer terminal convolution of a toilet tissue cant or similar roll product to the convolution immediately subjacent the tail. The tail of the roll product is secured by means of adhesive, and the method includes the step of ejecting a predetermined quantity of adhesive directly onto the subjacent convolution of the roll product while the tail is unwound therefrom. The adhesive is distributed along the length of the cant at spaced apart locations adapted to underlie the rewound tail, thereby allowing the tail to be adhesively secured to the cant. The apparatus includes adhesive applicator structure comprising a plurality of modules each of which is releasably secured to the apparatus so that it can be removed therefrom and replaced as an integer; and each adhesive applicator module includes a plurality of dispensing nozzles operative to eject a measured quantity of adhesive onto a cant underlying the same. The apparatus is fully adjustable to enable the angular location of the adhesive pattern to be changed relative to the length of the tail intended to overlie the same, and to enable the adhesive pattern to be oriented axially along the length of the cant in accordance with the size of the individual rolls into which it is to be subdivided.
