A method of producing material in the form of a material web (4) that has discrete pieces of material (6) mounted thereon without the using 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 a bonding or fastening (5), such as ultrasound welding means, wherein the anvil roll (2) forms a counterpressure means for a coaction with the cutting means (1) and the bonding means (5), wherein said roll includes said 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).
A method of producing material in the form of a material web that has mounted thereon discrete pieces of material intended for use in the manufacture of absorbent articles, said method comprising the steps of:
An arrangement for bonding or joining discrete pieces of material to material in the form of at least one travelling web, intended for use in the manufacture of absorbent articles, said arrangement comprising an anvil roll which rotates about its longitudinal axis and forms a counterpressure means of a cutting means for cutting discrete pieces from at least one material and of a bonding means or fastening means, the cutter and the remaining parts of the bonding means being located at different locations around the periphery of the anvil roll, the cutter being placed first as seen in the direction of rotation of the anvil roll, wherein the anvil roil includes holding means for holding said discrete pieces to said web with the aid of said bonding means, and the arrangement includes means for holding the web In abutment with the anvil roll before and after passage of the bonding means.
