Embodiment Construction

[0036] exist figure 1, it can be seen that the fabric tube 1 is fed to the device in the direction of arrow 2 and conveyed in the longitudinal conveying section 3 of the device in the direction of arrow 2 . First, the fabric tube 1 is cut along cutting lines 4 , 5 and 6 . The course of the cutting lines 4, 5 and 6 is depicted as dashed lines on the left, with line 4 extending across the entire width of the fabric tube 1 and lines 5 and 6 each extending across the edge 7 of the fabric tube. Cuts along the lines 4 , 5 and 6 are produced by means of a cutting device 8 . The cutting device 8 comprises a built-in tool, ie arranged between the fabric layers of the fabric tube 1 , comprising a roller 9 for separating the fabric layers and a plate-shaped tool 10 arranged behind the roller 9 in the conveying direction 2 . The plate-shaped tool 10 is used as the counterpart of the cutting tool, which acts on the fabric from the outside. The cutting knives operating along the cutting ...

Abstract

In a device intended to close a bag made of fabric and to which a tubular bag body can be fed, an adhesive application device is included for continuously applying adhesive in the bonding area, and also includes a device for applying The tubular bag is conveyed in a direction transverse to its longitudinal axis through a conveying device of the bonding region, which allows adhesive to be applied to the strip-shaped region of the tubular bag; adhesive removal device is provided, the An adhesive removal device, separate from the delivery device, is arranged below the bonding area for removal of adhesive applied by the adhesive application device in the spaces between the individual tubular bags.

Description

technical field [0001] The invention relates to a device for closing bags made of fabric, to which a tubular bag body can be supplied, comprising: an adhesive application device for continuously applying adhesive in the bonding area and a A conveying device for conveying the tubular bag transversely to its longitudinal axis through the bonding region, whereby adhesive can be applied to the strip-shaped region of the tubular bag. [0002] The invention further relates to a method for closing a bag made of fabric, wherein tubular bags are conveyed transversely to their longitudinal axis by means of a conveying device, wherein said tubular bags are spaced apart from each other in the conveying direction, and said closing comprises Adhesive is applied continuously at the bonding area, whereby the adhesive is applied to the banded area of ​​the tubular bag. Background technique [0003] The tubular body of the bag is usually formed from tubular circular material or flat material...
