METHOD FOR FORMING A HOSE COMPRISING A FLAT WEB MATERIAL AS WELL AS A HOSE FORMATION DEVICE AND A SYSTEM FOR PRODUCING BAGS

摘要

The invention describes a method for forming a hose from a flat web material, in which a flat web is supplied via a feeding device, the edges of the flat web material are folded by at least one hose formation tool, with the edge sections subsequently overlapping, parts of the overlapping edge sections are connected to each other. It is novel and inventive that the target position of at least one edge is determined after the edges have been folded over, that the actual position of at least one edge is determined by a measuring device, and that in case of a deviation of the actual position from the target position the hose formation tool is moved at least perpendicular in reference to the direction of transportation of the flat web material via an actuator.

1. Method to form a hose from flat web material, in which
a flat web is supplied via feeding devices; the edges of the flat web material are folded over by at least one hose formation tool with the edge areas subsequently overlapping; parts of the overlapping sections are connected with one another; the target position of at least one edge is determined after the folding over of the edges; the actual position of at least one edge is determined using a measuring device; and in case of a deviation of the actual position from the target position the hose formation tool is moved via an actuator at least perpendicular in reference to the direction of transportation of the flat web material characterized in that the measuring device is moved along with the hose formation tool and the current position becomes the new target position.
