Abstract: This invention relates to a method of sewing large area sewing material consisting of plural and at least two layers, of which at least one layer is formed of an elastical material, for instance foamed material, wherein said layers are fed to the sewing unit in a superposed relationship and wherein the layer of elastical material is fed to the sewing unit in an unexpanded and preferably bulged condition and is stitched together with the layer formed of non-elastical material. Such a method offers the advantage that the formation of folds in the stitched product is prevented in a simple and inexpensive manner.

Abstract: A device for transferring continuously arriving articles, especially folded-bottom boxes lying with their ends that face each other along the direction of travel differing in thickness, to a packing machine, with a mechanism for distributing the articles onto two different conveyor mechanisms, one conveying the articles without rotating them to the upstream side of a merging mechanism and the other extending below the merging mechanism, through a 180.degree. curve, and back to its downstream side and a mechanism for alternately laying off flat articles, especially folded-bottom boxes, from each side of and onto a more or less horizontal merging mechanism that is especially intended for use with a device of the aforesaid type and that has two two-belt conveyor mechanisms that end at approximately the same level on each side of and outside the layoff area. The merging mechanism is a conveyor belt that branches off at an angle from the two conveyor mechanisms and extends to a packing machine.

Abstract: A device for introducing material into containers with a material-release mechanism and with a structure that supports a container below the material-release mechanism and that can advance the container past the material-release mechanism. The supporting structure has a rocker bearing on which the container rocks back and forth. The point at which it supports the container is displaced to the rear as the container travels forward such that the displacement in the center of gravity of the container as it fills up both occasions an advance in relation to the material-release mechanism and brakes it as the container advances.

Abstract: The conveying apparatus for a flat article, particularly a cardboard blank, paper sheet or the like, comprises two driven endless belts running over guides positioned opposing each other between which the article is clamped during transport. The endless belts are guided on base surfaces of beds of the guides having a wavelike longitudinal cross section in the conveying direction with a plurality of wave troughs and peaks. A plurality of lateral supporting members are attached to each of the beds. The wave crests of one of the guides are positioned staggered with respect to the wave crests of the other guide and opposing the wave troughs of the other guide. Furthermore the endless belts are either elastic in the conveying direction or a tension provider is mounted engaging each of the endless belts.

Abstract: The invention relates to a method for blowing away particles of glue in a strip-gluing unit for folding box forming machines for gluing box blanks. Compressed air is blown from the side of a gluing disc of the gluing unit at an acute angle obliquely towards the direction of travel of the blank at the height of the nip between the blank and gluing disc so that on account of the high speed of the blanks and gluing disc, particles of glue which are thrown off are removed on the shortest path, without these particles splashing on the blanks and machine parts. The air is blown by an air-guide member, which comprises an air chamber, which is connected by lines to a source of compressed air. Starting from the air chamber is a bore whose axis is directed at the height of a nip at the acute angle. The air-guide member is attached in the folding box sticking machine independently of the gluing unit and is seated laterally beside the gluing disc and serves simultaneously to support the travelling blanks.

Abstract: A folding-carton gluing machine comprising a machine frame, an inserter, conveying means for the flat carton blanks, a crossbeam on the frame, carton working tools slidably mounted on the crossbeam, means for adjusting the position of the tools relative to a blank, the tools being movable from a working position which they are to occupy in the machine into a position in which they are spaced from the working position, and a sliding table for a flat carton blank adapted to be moved under the tools when the latter are spaced from their working position.
