Patent
CA 2010339
An apparatus is disclosed which serves to apply reinforcing slips provided with a glue coating to a web which has transverse perforation lines, preferably to a web that consists of bags, which are joined at the trans- verse perforation lines, comprising means for tearing from the web the sections or bags which are joined at the transverse perforation lines. A belt conveyor is provided, which consists of spaced apart endless conveyor belts, which are trained around receiving-end belt pulleys. A conveyor roller is disposed above said receiving-end reversing pulleys and urges the incoming web against the reversing pulleys. The conveying belts of the upper course are supported by a supporting roller, which is spaced behind the receiving-end reversing pulleys by a distance which is smaller than the spacing of the transverse perforation lines of the web. The supporting roller constitutes a backing roller for cooperating with a rotating segment, which has a cylindrical peripheral surface and serves to hold and transport the reinforcing slips. The radius and the surface speed of the peripheral surface of said segment are so selected in dependence on the length of the sections of the web that said segment urges each section of the web against the backing roller and causes a portion of each section of the web to be in rolling contact with the backing roller between two conveying belts. The surface speed of the segment and of the backing roller exceeds the conveying speed of the belt conveyor so that a slip is stuck on each section and each section is torn from the web.
