摘要:
The present invention relates to a cloth feed mechanism that can easily change a mode of a cloth feed section, and to a cloth bonding apparatus. The cloth feed mechanism feeds cloths to which adhesive is adhered, on a downstream side of a nozzle in a feed direction of the cloths. The cloth feed mechanism includes a motor drive portion, a roller support portion and a belt. The motor drive portion stores a third motor. The third motor has an output shaft that extends in a direction orthogonal to a long side direction of the cloth feed mechanism. The roller support portion supports a lower roller. The belt transmits power of the third motor to the lower roller, inside the cloth feed mechanism. The motor drive portion and the roller support portion can be separated from each other and coupled together.

A roller support portion 70 of a cloth feed mechanism 12 extends in an up-down direction, and a leading end portion of the roller support portion 70 is provided with a lower roller 13. In a cloth bonding apparatus 1, the cloth feed mechanism 12 is disposed below an upper roller 18, and the upper roller 18 comes into contact with the lower roller 13. The lower roller 13 rotates to transmit power of a drive motor 14, which is provided on a base end portion of the roller support portion 70. The cloth feed mechanism 12 feeds cloths clamped in a position where the lower roller 13 and the upper roller 18 face each other. The cloth that forms curved surfaces of a three-dimensional shape or the like after bonding does not interfere with the roller support portion 70 that extends from the lower side toward the facing position.

Disposable hygiene pants with a front portion (2), a rear portion (3) and a crotch portion (4) provided with two leg openings (5, 6), the longitudinal edge portions (21, 22) of the front portion being connected by longitudinal weld scams (7, 8) to the longitudinal edge portions (31, 32) of the rear portion (3) in order to form a waist opening (9) and two leg openings (5, 6) in the crotch portion, which leg openings are outwardly delimited in the transverse direction by the inner end portions of the weld seams as seen in the longitudinal direction of the hygiene pants. The hygiene pants have an outer cover (10), which is preferably elastic, and comprise an absorption unit (11). The cover is made of an elastic laminate comprising an elastic film applied between two nonwoven layers. The weld seams (7, 8) are each reinforced by at least one strip of reinforcing material (15, 16) containing thermoplastic fibers that is affixed to the cover using adhesive placed proximate to but preferably not in the area of the welds.

The invention relates to a method for forming a filter mat (1) suitable for filtering fluids, comprising at least one web section (39) of a mat web (9), at least one welding line (13, 15, 41) that seals the layers of at least one web section (39) of the mat web (9) to each other being formed. The invention is characterized in that subsequently at least one cut (19, 37) is carried out along the at least one welding line (13, 15, 41) such that the at least one web section (39) is cut forming at least one sealed edge region (43).

The present invention relates to a device for continuous welding of two films, one made of paper and one of plastic used to manufacture sterile packages for the containment of surgical instruments. The device according to the invention comprises: - first means (2,5) to preheat a first layer of film of paper material (F1); - second means (3, 6) to preheat a second layer of film of plastic material (F2); - a welding unit (4) capable of continuously welding of said first film F1 and of said second film F2 to form at least a tubular element welded at the side edges; characterized by the fact that the welding unit comprises at least one pair of heated rotating wheels (7) in contact with a motorized heated roller (9) at a point of pressure (PS) and a tensioner capable of keeping these films (F1, F2) overlapped and in contact with the outer surface of the heated wheel for some distance between a point of contact (PT) and the pressure point (PS) to allow the welding of the two films while they are in contact with the outer surface of heated wheels (7).
