Method and device for controlling the position of a web guiding or deforming station relative to a web

The present invention relates generally to a Method and apparatus for controlling the position of a web guiding and deforming station relative to a Web that is fed to it and then. Further is designed or shaped. The subsequent enormous may include redesigning the web into containers, bags, packs, pouches, strips of bags, and the like. close «■

continuous length of elastic material and in particular to a novel arrangement and method that a plow or a J ^! Give ilmforiners the opportunity to orient themselves relative to the flexible material that is fed to them.

In accordance with an important embodiment of this invention, tabs in a packaging apparatus can be formed from a continuously moving strip-like web by folding the strip into an elongated V-shaped channel and then forming transverse seams at spaced intervals along the length of the strip - One of the stages in this embodiment is the initial forming of eggim or flexible material into the elongated V- shaped channel *. In order to form the V-shaped channel precisely, the strip-shaped web is preferably folded evenly along a predetermined longitudinal line. When the ffibre-shaped web is folded in this way, the long side walls have an even height, and the subsequently formed pockets have an even volume and equal size can be »to form a U-shaped channel - if so desired.

The way it is shown is the strip-shaped orbit generally folded by the use of a plow, who shapes the flat strip into a funnel, when he joins one another in a longitudinal direction Machining process moves »The one deformed into a funnel Strip is then at a point in front of the plow head pinched. Up to now, however, it has been customary in the packaging industry to place the plow head on the former on the Keep packaging device firmly attached, with the result that transverse movement of the strip too an uneven splitting of the strip and one subsequent production of unsuitable packaging leads. The present invention relates to the development of a new method and device Eliminate the longstanding problems that through the use of the process and machines occur, which are used before and also today by bag or packaging manufacturers. It came from— exhibited that transverse or shifting movements of the longitudinally moving strip-shaped path through irregular Winding up of the Eilmes or the flexible Material onto the web feed roll or by other Details in the devices for feeding the strips shaped orbit or Eilmes to the e-flight device

Accordingly, it is a primary objective of this invention to provide a machine with an improved device that is mechanically guided by the force of the web is .. As it is shown, the path guided in this way can result in uniform packagings or Bags of a longitudinally moving strip-shaped Web are deformed.

It is also an object of this invention to provide an improved Device and method for controlling a, self moving web in the longitudinal direction to create the Edges of the strip in controlled relationship to each other and to a deformation area or station -hold into which the web is inserted.

It will be noted that it is not necessary that the moving "-3ao.il IJ be dead at its length; is achieved, and this is achieved by maintaining a constant relationship between the run away from the bay and the shaped edge 51 of the flying head 50.
