20190374392 · 2019-12-12 · ·

An absorbent article includes: a first sheet-like member; a second sheet-like member; an elastic member that is inserted along a lateral direction between a pair of mutually-opposing facing surfaces of the first sheet-like member; joining portions that join the pair of mutually-opposing facing surfaces and that are spaced apart in the lateral direction; and side-seal sections that are disposed at each lateral end portion of the absorbent article. The joining portions are disposed on two sides of the elastic member in a vertical direction, which intersects the lateral direction and a front-rear direction, so that the elastic member is sandwiched and pressed between the joining portions.

BUFFERING GAS CUSHION MACHINE
20190240921 · 2019-08-08 ·

Disclosed is a buffering air cushion machine, wherein the angle between a heat-sealing cooling transmission module as a core component of the buffering air cushion machine and a horizontal plane is between 20-50 degrees, thus greatly decreasing the transverse dimension of the buffering air cushion machine, so as to decrease the size of the whole machine and decrease the space occupied by the buffering air cushion machine; an inflation guide rod of a bent type may release some tension on a sealing side (an inflating passage) of a air cushion film, and may prevent wrinkles and bends from forming on the sealing side of the air cushion film during heat-sealing, so as to improve the quality of heat-sealing; furthermore, an upper coiling film guide rod and a lower coiling film guide rod may block the inflating passage connecting two air cushion films, and may prevent the air in the air cushion film which is filled with air but not sealed yet from travelling forward, so as to form a sealed high-pressure region and maintain the pressure in an inflation region, thus maintaining the pressure in the air cushion film after heat-sealing.

Strap welding system and method

Strap welding system and method for welding two ends or sections of a strap around a bundle of articles or around a pressed bale. The strap welding system has a weld assembly for frictionally welding two ends of a plastic strap around a pressed bale. The weld assembly has a weld head with an upper weld jaw and a lower weld jaw, and wherein the lower weld jaw is supported, directly or indirectly, by a spring. A connecting piece for moving the lower weld jaw can optionally have a section with a connecting spring.

Production method of elastic composite sheet, elastic composite sheet, and disposable wearable article using said elastic composite sheet

In a production method of an elastic composite sheet, the elastic member does not break when the elastic member, in a stretched state, is bonded to a base material sheet; an elastic composite sheet and a disposable wearable article use the elastic composite sheet. A strip-shaped or string-shaped elastic member composed mainly of a thermoplastic elastic resin is stretched in the longitudinal direction of the elastic member. The stretched elastic member is placed over a first base material sheet such that the main surface of the first base material sheet contacts the elastic member. In this state, the elastic member and the first base material sheet are bonded in a first position that overlaps the elastic member seen from a direction perpendicular to the main surface of the first base material sheet and that is away from the edges of the elastic member.

Method and device for applying at least one decorative strip to a seat cover

A device for applying a decorative strips (3, 4, 5, 6) with positional accuracy to a seat cover (2) with high-frequency welding, includes two tool halves (10, 30), of which one tool half has at least one electrode (14, 15, 16, 17). A first tool half (10) has at least two electrodes (14, 15, 16, 17) oriented parallel to each other, the width of the electrodes being adapted to the width of the decorative strips (3, 4, 5, 6) to be applied. Insulators (18, 19, 20, 21, 22) oriented in parallel are arranged between the electrodes (14, 15, 16, 17) and in parallel on the outside of the electrodes. The insulators (18, 19, 20, 21, 22) protrude beyond the electrodes (14, 15, 16, 17) in the direction of the second tool half (30). The insulators (18, 19, 20, 21, 22) are height-adjustable relative to the electrodes (14, 15, 16, 17).

Gasket Welding Apparatus
