A METHOD AND ARRANGEMENT FOR PRODUCING WEBS OF MATERIAL THAT HAVE DISCRETE PIECES OF MATERIAL MOUNTED THEREON

摘要

A method of producing material in the form of a material web (4) that has discrete pieces of material (6) mounted thereon without the use of an adhesive agent and while using only one single anvil roll, and an arrangement (10) for carrying out the method and comprising an anvil roll (2) which rotates about its longitudinal axis and which is intended to be partially embraced by or be tangential to said web (4), said roll (2) carrying sequentially as seen in its direction of rotation at least one cutting means (1) for cutting discrete pieces from a material (6), and bonding or fastening means (5), such as ultrasound welding means, wherein the anvil roll (2) forms a counterpressure means for coaction with the cutting means (1) and the bonding means (5), wherein said anvil roll includes holding means (7) for holding the cut discrete pieces of material (6) against the roll (2) prior to bonding or fastening said discrete pieces to said web by means of said bonding means (5).
