Embodiments of the present invention may include beading for decorating a target member. The beading has a linear member, a leg portion and a colored portion. The linear member has a main portion formed of a light-transmitting material. The linear member has a first end and a second end opposite the first end on an outer periphery thereof. The leg portion extends from the first end of the linear member. The leg portion has a sewn portion that is sewn onto the target member by sewing thread. The colored portion is provided in the linear member or the leg portion. The colored portion has a smaller quantity of transmitting light than that of the main portion. The colored portion is situated and configured to suppress the visibility of the sewing thread when the linear member is seen from above the second end.

Beadings

Provided is a slider which is lightweight, reduces production cost and is excellent in quietness, the slider having a slider body which is hardly deformed or broken. The slider includes a slider body made of synthetic resin and a slider handling tool which holds a top and bottom of the slider body and performs sliding operation. The slider handling tool has first and second arm parts connecting with a connecting axis part and first and second holding parts disposed at a tip end part of the first and second arm parts, respectively.

Slider and handling tool for slider

A belt member includes: a strip member having an elongate shape; a fastener disposed along the longitudinal direction of the strip member; and an opening-closing device that opens or closes the fastener. For reducing a contact pressure of the belt member per unit area, the fastener is opened by the opening-closing device to unfold the belt member into a form of a wide strip so that the width of the belt member is increased. On the other hand, when the fastener is closed by the opening-closing device, the belt member takes a form of a narrow tube so that the width of the belt member is reduced.

Belt member and seatbelt apparatus including the belt member

An apparatus and method for manufacturing a slide fastener. The apparatus may provide a chain transfer path inclined downward for transferring a fastener chain, a chain cutting portion disposed at a middle of the transfer path and a feed portion disposed on an upstream side of the chain cutting portion of the chain transfer path. A control portion may also be provided for a) stopping to transfer the fastener chain by the feed portion and b) operating the chain cutting portion. A pivoting section may also be provided, which pivots the chain cutting portion by a predetermined angle on the chain transfer path around an axis line orthogonal to the transfer path.

Slide fastener manufacturing apparatus

The invention is a continuous finishing apparatus for a slide fastener having a slider introduction portion for successively introducing a slider by intermittently running a slide fastener chain, wherein, a slider introduction member thrusts into the space portion when the slider held by a slider holding member is brought into a space portion and set therein, moves downstream of the slide fastener chain within the space portion, holds an engaging element disposed at a downstream end portion of the space portion, and then, continues to move to the downstream for carrying the slide fastener chain, and wherein the slider is introduced and set along the same chain upon this carriage. Because the slider introduction member carries the slide fastener by holding the engaging elements on an edge of the fastener tape, which is least elongated, no disagreement occurs in position of corresponding right and left engaging elements.

Continuous finishing apparatus for slide fastener

In a slide fastener chain sewing apparatus, a continuously supplied slide fastener chain is successively sewn onto a pair of left and right cloth pieces. A chain cutter cuts the slide fastener chain between the cloth pieces which are moved continuously over a sewn product transfer device table and suspending from a front end of the table. A sewn product receiving section has sewn product transfer means for receiving, in a lower part, a sewn product cut away from the succeeding cloth piece having the fastener chain sewn thereto. The sewn product transfer device transfers the sewn product to a rear end of the table through a lower space portion of the table.

Apparatus for sewing slide fastener chain onto cloth piece

A drilling apparatus, in which a hole and an insertion hole for a drilling rod are formed at a drilling position of a table and at a sheet pressing member capable of approaching or leaving a surface of the table, respectively, the drilling rod made of metal, capable of rotating at high speeds and reciprocating vertically are inserted through the both holes, the drilling rod has smooth peripheral and front end faces composed of at least part of a circular section having no blade, and a predetermined clearance is provided between the diameters of the hole and the insertion hole and the diameter of the drilling rod, whereby by pressing the drilling rod rotating at high speeds to the sheet, a sheet material is melted by frictional heat so that a beautiful hole is formed.

Drilling apparatus for flexible sheet made of thick thermoplastic material

A method of forming successive space portion in a slide fastener chain, comprising: positioning the chain in such a manner that an element contiguous to the backward end of a prospective space portion is brought into engagement with a positioning pin upstream of a cutting unit; positioning the chain in such a manner that an element contiguous to the forward end of the prospective space portion is out of engagement with another positioning pin downstream of the cutting unit, and then positioning the chain, as the feed roller is rotated forwardly to extend the chain so that the positioning pin is inserted between the elements, whereupon the downstream positioning pin is brought into engagement with the element adjacent to the prospective space portion as the feed roller is rotated backwardly to restore the slide fastener chain; and cutting off elements of the prospective space portion and removing the cut elements from the prospective space portion.

Method of forming space portions in slide fastener chain

A process for the manufacture of slide fasteners from an elongate stringer chain is disclosed in which the stringer chain is maintained in tensionless suspension at predetermined locations along the path of its movement through various stages of production. A plurality of processing units are controlled so as to operate in synchronized relation to one of such units which has a slowest cycle of operation.

Process for the manufacture of slide fasteners

A method is disclosed for manufacturing slide fasteners from a single homogeneous elongate stringer chain or a stringer chain comprising a plurality of interconnected stringer chains of different characteristics having first standard element-devoid space portions. The method comprises marking the stringer chain at spaced apart locations by providing second element-devoid space portions greater in length than the first standard space portions and detecting the second space portions to trigger operation of respective operative units in the manufacturing apparatus.
