摘要 |
The present invention relates to apparatus for joining a first web (8) consisting of plastic material to a second web (9) consisting of absorbent material, wherein the arrangement includes a cooling-roll (1), a counter-roll (2), and means for feeding the first and the second webs through the nip defined between the cooling-roll and the counter-roll, the webs being pressed together in the nip, and wherein the plastic material in the first web (8) is in a plastic state when entering the nip. According to the invention a pattern of moulds (5) having air-permeable bottoms is arranged over at least a part of the mantle surface of the cooling-roll (1) and a vacuum box (7) is arranged inwardly of the cooling-roll mantle in the region of abutment of the first web (8) with the cooling-roll. The inventive apparatus also includes cooling devices (3, 4) for cooling the cooling-roll mantle from outside the roll. |
