Provided is a button fastener-side die. The button fastener comprises an annular base defining an opening and a plurality of legs. The button fastener-side die includes a holding part for holding the button fastener and a correcting member for passing through the opening of the button fastener held by the holding part, a pushing member for pushing the correcting member to move in a passing direction toward passing through the opening of the button fastener, and a first spring disposed between the correcting member and the pushing member. When at least one of the legs of the button fastener is in an abnormal position, the correcting member corrects the abnormal leg(s) to be in the normal position as the correcting member is passing through the opening.

Button fastener-side die for attaching snap button

A button fastener transfer device can detect a fastener with one or more legs are bent radially outward. The button fastener transfer device includes a transfer path for passing the fastener with the base down; a movable member movable in the transfer path for moving the fastener downstream in the transfer path; a rotation applying part capable of contacting the fastener moving in the transfer path and configured to rotate the fastener in the circumferential direction of the base; at least one first conductive member and at least one second conductive member, which are normally electrically isolated from each other; a detection part configured to detect a non-normal fastener having at least one non-normal leg bent radially outward; and an energization mechanism configured to cause an electric current to flow between the first conductive member and the second conductive member if the detection part detects the non-normal fastener.

Button attachment member conveying device

An attaching apparatus, which attaches an attachment object to a fabric using a fastening member, includes at least one pair of first holding members configured to hold an attachment object; and a first die configured to hold the attachment object at a terminal of a die main body. The first die moves such that the attachment object, held at the at least one pair of first holding members, is held at the terminal of the die main body and then the attachment object is placed onto the fabric. The attachment object is transferred from the at least one pair of first holding members to the first die at a position distanced away from the fabric.

Attaching apparatus and method for attaching attachment object to fabric using fastening member

There is provided an end stop. A male member and a female member are configured to sandwich opposing side edge portions of a pair of fastener tapes from both sides thereof in an upward and downward direction. The male member includes a circular disk-shaped male base member and an inserting male portion. The female member includes a circular disk-shaped female base member and a receiving female portion. A facing surface of at least one of the male base portion and the female base portion is provided with a protrusion group. The protrusion group is configured so that a plurality of protrusions protruding to come at least in contact with each fastener tape are arranged to be spaced from each other at predetermined angles over the entire circumference of the facing surface along a circumferential direction thereof.
