Problems solved by technology
The method of heat welding is to clamp the sheet between the rollers and pressurize it, and heat it to high temperature at the same time. There are protrusions on the outer surface of the rollers. If the curved telescopic parts contact the protrusions, the elastic parts can be cut off by heat or pressure. so the equipment is expensive
In addition, heat welding needs to heat the sheet material to the melting point at a predetermined time, which cannot speed up the production speed, and cannot improve productivity

Embodiment Construction
[0072] The present invention will be further described below in conjunction with the accompanying drawings and embodiments of the specification.
[0073] figure 1 It is a perspective view of a composite telescopic part according to an embodiment of the present invention, figure 2 for figure 1 A-direction view, image 3 for figure 1 floor plan. The production method of composite telescopic part 1 is: vertically ( figure 1 The X direction of the two long sheets 2 and 2a are superimposed in alignment and a plurality of elastic members 3 extending longitudinally along the sheets 2 and 2a are sandwiched between the sheets 2 and 2a so as to be substantially parallel to each other. The sheets 2 and 2a are made of non-woven fabric or the like, and the elastic member 3 is made of a belt-shaped body such as a rubber thread. The sheets 2 and 2a are joined at a linear joint 4 along a direction perpendicular to the longitudinal direction of the sheets 2 and 2a ( figure 1 The Y dire...

The invention relates to a wearing article provided with a composite telescopic part and a production method thereof. Composite telescoping parts are produced by sandwiching an elastic member between two sheets, joining the two sheets, wherein the possibility of the elastic member being severed is low. The production method of the composite telescopic part (1) is: longitudinally align and superimpose two long sheets (2, 2a), and a plurality of elastic parts (3) elongated longitudinally along the two sheets (2, 2a) and approximately parallel ) is sandwiched between two sheets (2,2a); the two sheets (2,2a) are joined to each other at the junction (4); the junction (4) includes a longitudinal direction perpendicular to the sheet (2,2a) The hot-melt material applied continuously in the direction; the joint part (4) passes through a plurality of elastic parts (3); two adjacent sheets (2, 2a) are formed between the joint parts (4), and pass through the elastic part (3 ), the plurality of folds (40) are elongated through the plurality of elastic members (3) perpendicular to the longitudinal direction of the sheet material (2, 2a).
Description
technical field [0001] The invention relates to a composite telescopic part, which is formed by longitudinally aligning and stacking two long sheet materials and sandwiching an elastic part extending longitudinally along the sheet materials between the sheet materials. The present invention also relates to a production method of the composite elastic member, and a wearing article (for example, a diaper using the composite elastic member) and a production method thereof. Background technique [0002] Patent Document 1 discloses a composite elastic member used for the waist of a diaper or the like. The composite telescopic part is formed by vertically aligning and superimposing two long sheets such as non-woven fabrics, and sandwiching elastic parts such as rubber threads extending longitudinally along the sheets between the sheets. The sheet is thermally welded intermittently in its longitudinal direction and transverse direction. The elastic part does not pass through the ...
