Embodiment Construction

[0030] figure 1 A splicing device 1 according to the invention is shown for forming a spliced ​​connection between a first or old film-like web 2 and a second or new film-like web 3 . The film-like sheet is in particular a cold-sealable film or a heat-sealable film, which can also be produced from the aforementioned rubber spacer film. The film-like web can then be fed by the splicing device 1 to at least one further processing station. The further processing station can be, for example, a packing station in which bulk goods or individual parts are packed by means of a rubber foil.

[0031] The splicing device 1 comprises at least two rotating shafts 5, 9 for receiving rolls with film-like sheets; and a pressing unit 11 for making or supporting said splicing. In the present embodiment there is a first axis of rotation 5 and a second axis of rotation 9, on which a first roller 4 is supported, the first roller 4 has a first film-like sheet 2, a second roller 8 is supported on th...

Abstract

A splicing method serves for connecting an active film web (2) which is wound up on a first reel (4) to a passive film web (3) which is wound up on a further reel (8). The active film web (2) is unwound from the first reel (4) and is fed to at least one processing station. When a remaining film quantity of the active film web (2) is reached on the first reel (4), the active film web (2) is spliced or connected to the passive film web (3), with the result that the passive film web is pulled by the active film web (2) into the at least one processing station and therefore changes from the passive film web into the active film web. Before the operation of splicing, the outer side (18) of the passive film web (3) is provided with a connecting element (19), and the active film web (2) and the passive film web (3) are moved towards one another before the operation of splicing, wherein the active film web (2) is pressed against the further reel (8) with the passive film web (3) and the passive film web (3) is thus spliced to the active film web (2) via the connecting element (19).

Description

technical field [0001] The invention relates to a method of joining two film-like sheets according to the preamble of claim 1 and a corresponding device according to the preamble of claim 9 . Background technique [0002] The rubber wrapping machine packs the product into a film, by deforming a rubber made from a film-like sheet around the product, forming sealed seams at the longitudinal and transverse edges and separating the individual bundles. The film-like web is led onto the machine in roll form, unrolled there, and fed to a film-like web processing station, such as a folding device. [0003] From the prior art eg EP0061788 it is known that the film-like web of the packaging machine is continuously fed by one roll, a second roll can be prepared. The first roll is mounted to join the first film-like web of the first roll with the second film-like web of the second roll by means of a splicing device to subsequently feed the film-like web of the second roll to the packag...
