APPARATUS AND METHOD FOR MAKING SIDE SEAMS ON ABSORBENT ARTICLES Russian patent published in 2018 - IPC A61F13/496 

FIELD: medicine.

SUBSTANCE: drum includes a fluid nozzle and a press member. According to disclosed method, a first elastic laminate and a second elastic laminate may be advanced in a machine direction onto the rotating drum. Fluid is heated to a temperature sufficient to partially melt substrate layers of the first and second elastic laminates. As the drum rotates, the press member shifts radially outward from the drum wherein a length, L, of the pattern surface extends in the cross direction across a plurality of elastic strands of first and/or second elastic laminates. And the partially melted portion of the substrate layers of the first and second elastic laminates and the plurality of elastic strands are then bonded together by being compressed between the pattern surface and the anvil roll.

EFFECT: present invention relates to methods and apparatus for bonding elastic laminates to each other by compressing them between a rotating drum and a supporting roller.
