The invention relates to a method of distributing opening devices and preparing the opening devices for application individually to a packaging containers. The opening devices are positioned, closed and marshalled together to form a web or a sheet. The prefabricated opening devices are arranged in rows of length x. Two or more of the opening devices in each row are provided with projections which are placed against corresponding opening devices in a neighboring row and are welded together using ultrasonic means.

Method of distributing objects

The invention relates to an apparatus for grouping objects in which objects on an ingoing conveyor are released in preselected numbers by a brake. The preselected number of objects pass one or two pushers which are arranged such that they execute a movement that is both transverse relative to the direction of an outgoing conveyor and synchronous with the outgoing conveyor. Where two pushers are used, they move in sequence so that a first pusher groups objects first, followed by the second pusher, and then both pushers remain in their position of rest, and the objects are grouped in three different rows on the outgoing conveyor.

Apparatus for grouping objects

Transport crate

A machine for loading articles such as milk cartons in a crate and stacking the crates for transport is described. The crate has folding sides. A supply of crates stacked in folded condition is introduced into the machine. The crates are removed individually from the stack by the machine, the sides are raised, and the crates are arranged vertically on a conveyor in preparation to receive the filled cartons. Cartons are inserted into a crate, which is then banded by a plastic strip, and the crate is placed in a stack with other crates that have been filled with cartons. The stack of filled crates is then unloaded from the machine.

Method and apparatus for loading and stacking crates

An apparatus for delivering in strip form packaged drinking straws, includes a device for severing the strip on a pivotal drum. The severing device pivots to transfer the individual packed straws to a vacuum cylinder, which is intermittently pivotal to pick up the individualized straws from the drum, and transfer the individual straws to a conveyor section. The conveyor section includes a continuous loop of track having an upper linear section of track and a lower linear section of track. A plurality of pressure arms are connected to the track where, each contains a vacuum holding mechanism adjacent to a free end for retaining the individual straws. The vacuum cylinder is mounted to a slide mechanism which is translatory relative to the upper linear section of the continuous track to position the individual packaged straws on the pressure arms of the conveyor mechanism. The pressure arms are pivotally controlled to pick up the individualized straws when the pressure arms are moving along the upper linear section and, when in the lower section of track, to position the straws adjacent to continuously moving containers to which the individualized packaged straws are attached.

Method of attaching a drinking straw to a pack and apparatus for

An apparatus for attaching drinking straws to a container includes a conveyor track for advancing containers and a rotating drum having a plurality of receiving areas located around its outer periphery for receiving the drinking straws. An applicator is provided for applying a bonding agent to the side wall of the containers. A device for transferring the drinking straws form the receiving areas on the drum to the side wall of the container after the bonding agent has been applied is also provided. After the drinking straws are attached to the side wall of the container, a device folds the drinking straws so that the drinking straw does not project beyond the edge of the container.

Arrangement for the attachment of bendable, elongated objects, in

A weblike package for suction tubes (1) comprising two straight tube parts (1a and 1b) which are joined flexibly by means of a bellows-folded, tubular intermediate part (1c). The package (2) comprises two flexible material webs which are joined to one another by repeated longitudinal and transversal sealing joints (6 and 7) which in pairs jointly form closed spaces (8) wherein suction tubes (1) are arranged. The suction tubes (1) are oriented straight with the free ends (1a' and 1b') of both their straight tube parts (1a and 1b) directed away from one another towards the longitudinal edges (5 and 5') of the material webs. Individual wrapped suction tubes (1) separated from the package are intended to be applied to the outside of a packing container with the longer straight tube part (1a) of the suction tube placed diagonally between opposite corners of the packing container, and with the shorter straight tube part (1a) of the suction tube bent parallel with the upper edge line of the packing container, and to make possible such an application of the wrapped suction tube without causing the surrounding envelope to burst the spaces (8) are provided with portions (8a, 8b and 8c) of mutually differing cross-sectional areas, the space portion (8a) in the region of, and closest to, the bellows-folded intermediate part (1c) having the largest cross-sectional area.

Packaging container with attached drinking straw

The disclosure relates to an apparatus for applying objects such as spoons or suction tubes diagonally to a side wall of a packing container. As the containers are advanced by a conveyor, a carriage reciprocates adjacent the conveyor. A rotary drum is mounted on an inclined axle on the carriage. The objects are supplied to the drum in the form of a band in which the objects are spaced apart. The drum holds the individual objects while they are severed from the band by a reciprocating knife. Rotation of drum positions each object in a correct angular position with respect to the side wall of the container. An adhesive applicator is also positioned on the carriage to apply adhesive to the side wall of the container. A transfer arm applies the object against the side wall of the container where it is retained by the adhesive.

Arrangement for the application of objects to packing containers

A method for the application of suction tubes to packing containers is disclosed. Portion-sized packages for juice and the like are often equipped with suction tubes to facilitate the emptying thereof. The suction tubes, which for reasons of hygiene are individually wrapped in paper, are very light and therefore difficult to handle and to attach to the outside surface of the packing container by mechanical means. The wrapped tubes are separated from a continuous band while an adhesive is applied to the containers. The containers and tubes ae oriented in relation to each other and then the tubes are attached to the containers.
