An apparatus for successively making plastic bags of plastic film, each of the plastic bags having a size, comprising an upstream feeder by which superposed layers of plastic film are fed intermittently along an upstream feeding path for a length which is N times as much as the size of plastic bag and at a cycle number; a heat sealer disposed in the upstream feeding path, the layers of plastic film being heat sealed by the heat seal means whenever being fed intermittently to obtain N times in number of plastic bags; a downstream feeder by which the layers of plastic film are fed intermittently along a downstream feeding path for a length corresponding to the size of plastic bag and at a cycle number which is N times as many as the cycle number of the upstream feeder, after being heat sealed by the heat sealer; a cutter disposed in the downstream feeding path, the layers of plastic film being cut by the cutter whenever being fed intermittently; and an accumulator disposed between the upstream and downstream feeding paths, the layers of plastic film being accumulated temporarily by the accumulator whenever being fed intermittently by the upstream feeding means, the layers of plastic film being then supplied from the accumulator whenever being fed intermittently by the downstream feeder; wherein N is an integer equal to or greater than 2.

A folding box gluing machine contains one upper and lower transport belt disposed on each side of the machine. A lower transport belt is guided in a roller cheek and an upper transport belt is guided in a roller rail. A central roller cheek and a central roller rail, which can be fed in, are further disposed in the center of the machine and in each case guide a central transport belt. A device for inserting side parts of a folding box blank, which side parts overlap and/or engage in one another, is provided. The device is fastened to the central roller rail and is driven by the central upper transport belt through a V-shaped belt. The device for inserting is held on a holding frame in a load bearing frame which can be fed in separately. The central roller rail is additionally fastened to the holding frame.

In the production of packs, especially hinge-lid packs, from rigid packaging material (thin cardboard), hitherto individual blanks have been supplied in stacks and introduced into the packaging machine in succession. To make the handling of the blanks easier and to increase the storage capacity, the blanks (23) are now connected to one another via residual connections (25) into a continuous web of material (24) wound as a reel (30). Within the packaging machine, the blanks are severed from the web of material (23) in succession, specifically as a result of the elimination of the residual connections, preferably by being torn off. The residual connections (25) are formed in a region of the blanks (23) or in the region of folding tabs of the latter which, in the finished pack (hinge-lid pack), are concealed by other folding tabs, that is to say are on the inside.

A vari-gap drive system for controlling the speed of the drive system used in the fabrication of corrugated boxes which varies the drive rate for a folder vis-a-vis that of the printer/slotter to which it is attached to vary the box blank gap through the folder and thus permit a throughout two to three times faster than that attainable when the drive for the two units are driven at the same speed. The reliability and speed of the subject Vari-Gap Drive System is in part derived from a unique cage roll assembly.

In a box-making machine a flat blank is passed longitudinally by a conveyor through a plurality of treatment stations at each of which a treatment element displaceable transversely to the conveyor acts on the blank to fold it up into a three-dimensional box. Each of the treatment elements is carried on a respective threaded spindle that can be rotated to position it transversely of the conveyor, and each spindle is connected via a respective electromagnetic clutch to a common drive chain. Also driven by this drive chain is a control spindle carrying a scanning device which can move past a blank or the like and generate a succession of position signals. The scanning device and the treatment elements are all jointly and synchronously displaced in one direction across the conveyor and as each of the position signals is generated the respective treatment element is arrested so that all of the treatment elements can be exactly positioned in one operation.

An apparatus for making bags from a continuously fed heat-sealable web comprises supporting bars for the web arranged on a rotary cylinder parallel to and at a spacing from one another. Means for transversely welding and separating the web comprise welding bars co-operating with backing bars. The backing bars are arranged between the supporting bars and are displaceable towards the welding bars. The supporting and backing bars are movable towards and away from one another in a zig-zag line during transference of the web passed therebetween. The supporting bars for receiving and holding the web are axially extensible and retractable at least over the width of the web. In the region of the cylinder sector in which the supporting bars are retracted and the separating weld seams are produced, the welding bars are guided to be concentric with the cylindrical enveloping surface swept by the backing bars, namely outside said enveloping surface and at the same angular speed.

The present invention relates to bag making machines, a particular embodiment of which comprises a system of two-way gates, a tubing machine which forms a tube of suitable material, cuts the formed tube into tube lengths and axially discharges the tube lengths into the system of two-way gates, a plurality of sewing machines and associated feed conveyors, the system of gates directing the tube lengths in a cyclic sequence to the sewing machine feed conveyors which transfer the tube lengths sideways to the sewing machines. The operation timing of the sewing machines and associated feed conveyors and the system of two-way gates is controlled with respect to that of the tubing machine drive.

Box parts such as box bottoms and box lids are fabricated from notched blanks of plastic sheet material.Relatively large boxes can be fabricated and the blank feed mechanism is actuated by a crank mechanism that runs at twice the speed of a main, one revolution per cycle drive shaft. An extension blank pusher can be added to produce smaller boxes. The tab folders have solvent applicators formed as grooved metal bars associated with a centralized solvent delivery and recovery system. The transverse folding dies are heated with a flexible, rope-like heating element to facilitate changes in die length. The feeding apparatus includes cam operated, vacuum cup lifter arm assemblies which lift the top blank from a stack and present it to vacuum cups on the feed pushers. These assemblies are longitudinally adjustable. The anvils that cooperate with the tab folders have heated bodies, but their clamp surfaces are insulated from the bodies.
