A double-sided engaging element for a slide fastener, comprising a central elevated portion elevated from a coupling base surface; and a pair of right and left projecting portions formed to project from a body portion toward the central elevated portion and to be elevated from the coupling base surface, wherein a central elevated portion of a mating element is detachably coupled in a dent surrounded by the central elevated portion, the right and left projecting portions and a stepped surface. A dimension (T) between inside elevation startup edges of the right and left projecting portions is set smaller than a dimension (R) between right and left elevation startup edges of the central elevated portion, and a first missing portion is formed on an outside corner of an end portion of each of the right and left projecting portions opposing the central elevated portion.

Double-sided engaging element for slide fastener

A fastener stringer continuous manufacturing apparatus which eliminates a necessity of increasing a size of a manufacturing apparatus and is capable of chamfering attaching legs of an engaging element which is produced continuously from a metallic wire rod having a Y-shaped section, securely and accurately, without changing a load and stroke of a pressurizing hammer, the manufacturing apparatus comprises a pair of chamfering punches each of which is disposed above the pressurizing hammer at a height corresponding to a preceding engaging element implanted to a fastener tape in advance, the chamfering punch reciprocating with respect to a side face of the preceding engaging element and having a chamfering face which chamfers outer ridge portions of right and left legs of the preceding engaging element.

Apparatus for continuously manufacturing fastener stringer

The invention provides a feeding unit for a metallic linear material having an irregular shaped section applicable to a continuous manufacturing apparatus for a fastener stringer, the feeding unit comprising the seventh and eighth rollers rotatably supported at their fixed positions, the ninth and tenth rollers opposing the seventh and eighth rollers and rotatably supported at both ends of a movable roller support member, wherein the roller support member is rotatably supported around its center and urged elastically in a direction perpendicular to a straight line connecting the centers of roller shafts of the seventh and eighth rollers, thereby the feeding roller protecting the metallic linear material from easily slipping out of feeding rollers, returning the linear material to its original track immediately even if the linear material slips out for a while, and feeding the metallic linear material stably and securely without damaging the linear material or ratchet wheel.

An air/water-tight slide fastener has an end stop. The end stop has a flange portion extending therearoud. At least part of the flange is extensive enough to be integrally fixed to the opening edges of an opening formed in an article. Since the flange portion is firmly clamped by and between the air/water-tight fastener tape and the opening edges of the opening of the article; when the air/water-tight slide fastener is folded on itself; the excessive bending stresses exerted directly on the air/water-tight fastener tape is relaxed or mitigated. The air/water-tight fastener tape is thus prevented from being peeled off at that position.

Air/water-tight slide fastener

A flexible container for liquid transport made of a flexible material includes a top face portion, a bottom face portion, and a peripheral face portion connecting the top face portion and the bottom face portion. An air tight, water resistant slide fastener is openably/closably mounted to the peripheral face portion of the container. A liquid stirring port is provided at the top face portion, and a liquid injecting and ejecting port are provided at a lower end of a rear face portion of the peripheral face portion. Container suspending pieces and bottom face portion fixing pieces are mounted at the top face portion of the container and at four corners of the bottom face portion. During washing, the container can be washed reliably and efficiently while the inside of the spread out container can be visually checked by efficiently utilizing the air tight, water resistant slide fastener, liquid stirring port, liquid injecting and ejecting port, and container suspending pieces, and bottom face port fixing pieces. Thus, according to the present invention, washing, sterilizing and disinfecting treatments and thereafter drying treatment by heating can be performed efficiently, with the container having higher strength, higher air tightness and water resistance.
