摘要:
A riveting press wherein the female component of a composite button, knob or a like article of hardware is introduced between the jaws of first tongs below a sheet of textile material whose marked side faces upwardly, and wherein the male component of the article is introduced between the jaws of second tongs at a level above the sheet. The first tongs deposit the female component on a stationary anvil while the second tongs descend toward the upper side of the sheet to place the male component into the path of movement of a descending ram which causes a deformable part of the male component to penetrate through the sheet and to be deformed into permanent engagement with the female component by a centering stud which is provided on the anvil. The mechanism which moves the first tongs up and down derives motion from the mechanism which moves the second tongs and the ram.

Male or female annular components of fasteners are applied to articles of clothing in a machine wherein the lower tool of a pair of confronting tools has a socket for reception of the heads of discrete rivet-like connectors whose shanks extend upwardly toward the upper tool which has tongs with jaws for releasably holding a male or female component in such orientation that the central aperture of the component is in register with the shank of the connector in the socket of the lower tool. The upper tool further includes a ring-shaped hold-down device for the male or female component which is held by the tongs as well as a deforming plunger which can upset the tip of the shank after the latter has penetrated a garment between the two tools and thereupon through and partly beyond the aperture of the component in the tongs in response to downward movement of the upper tool. The hold-down device is movable axially relative to the tongs and the plunger is movable within limits axially of the hold-down device. The male and female components of fasteners are stored in discrete magazines and are fed to the tongs by devices whose operation can be blocked so that the tongs receive male or female components.

An apparatus for attaching a pair of fastener elements onto a garment includes a gripping mechanism for temporarily holding one fastener element and for releasing the latter immediately before a reciprocally punch arrives at the predetermined lowermost position in which the one fastener element is clinched to the other fastener element supported on a die with the garment sandwiched between the fastener elements. The apparatus may comprises a guide mechanism including a chute having a guide track for the passage of the one fastener element, and a speed reducing device disposed in the chute for slowing down the movement of the one fastener element prior to the arrival of the latter at a retaining portion of the gripping mechanism. An overturning device may be provided in the chute for turning over the one fastener element as the latter slides along the guide track.

A snap fastener and method of attaching the same to a section of sheet material are disclosed. The snap fastener comprises an operative component and a securing component, both of these components being formed of plastics material. The operative component has a base wall with an opening therethrough and a tubular portion including a snap engaging portion formed thereon surrounds the opening and projects from one side of the base wall. The securing component has a pin and a cap flange at one end thereof, the pin being adapted to pass through the opening of the operative component so that the terminal end portion of the pin is located beyond the side of the base wall from which the tubular portion projects. The terminal end portion of the pin is deformable when so located relative to the operative component so as to secure the two components against separation. At least a peripheral portion of the cap flange slopes outwardly in a direction towards the terminal end of the pin. The method of attaching the fastener to a section of sheet material includes the steps of causing the pin to pierce the sheet material, locating the operative component over the pin so that the sheet material is interposed between the cap flange and the base wall and the pin projects through the opening so that the terminal end portion thereof projects beyond the base wall. Thereafter, pressure is applied to the terminal end of the pin to deform same to an extent such that the pin cannot be withdrawn out of the opening. Axial pressure is additionally applied to both of the components to press them together and thereby reduce or remove by deformation the slope of the cap flange, this axial pressure also being maintained during the deformation of the pin terminal end.
摘要:
An apparatus for attaching a pair of fastener elements onto a garment comprising a plunger reciprocably mounted in a bored head for movement along a path toward and away from a stationary die mounted on a table in opposite relation to the bored head, the plunger having a punch for coacting with the die to attach the pair of fastener elements onto the garment from opposite sides thereof, and first and second means mounted respectively on the bored head and on the die for releasably holding the fastener elements in the path in front of the punch and the die. The first means is actuatable by the punch for releasing the one element. The second means is responsive to coaction with the first means for releasing the other element.

An improved feed arrangement is disclosed for feeding two component fasteners, such as buttons, snaps and the like having a pronged element and a backing element, to an apparatus which attaches the fasteners to material, such as a garment. The feed arrangement for each component includes a hopper-chute assembly, a guide channel and a driving means. Each hopper-chute assembly is readily detachable from the apparatus to provide rapid substitution of one type or style of fastener for another and includes means preventing discharge of elements from the chute when the assembly is detached from the apparatus. The guide channel and drive means are arranged to receive elements from the chute and move them successively in a single step to a setting station where an anvil and a ram forcefully bring the elements together. The guide channel for the pronged elements is formed by a pair of spaced, opposed wall members spring biased towards each other. The wall members have faces of non-linear shape and taper towards each other in the direction of feed to form a labyrinth configuration therebetween. This configuration serves to align the prongs with the axis of the channel so that they will not be prematurely and unwantedly deformed by jaws on the anvil.

High speed apparatus and method for affixing male or female snap fasteners to a moving web of material are described. The web is advanced continuously, while snap fastener components are periodically positioned in recesses on rotating platens above and below the web. The platens are synchronized with web velocity, and as the snap fastener components rotate and are brought into contact with the web a pressure is applied between the platens to affix the components to each other through the web.

Apparatus for attaching plastic snap fasteners to an article of clothing or the like including a plurality of snap fastener attaching machines mounted in spaced relation to each other on a cylindrical rod permitting each attaching machine to be adjustably spaced from the adjacent attaching machine and permitting each attaching machine to be pivoted away individually from the other machines for servicing and for refilling with snap fastener elements.
摘要:
A machine for attaching the components of a snap fastener to a material, wherein the snap fastener components are fed from strips in spaced relation to each other, are separately cut from the fed strips and are clamped together with the material therebetween by means of a ram and cooperating anvil; the feeding, cutting and clamping operations are performed in a particular sequence and are performed automatically upon initial operation of a control device.

An automatic fastener-attaching machine has a garmenttransporting mechanism which automatically moves a garment past the fastener-attaching station and automatically stops the movement of the garment for the attachment of each fastener. The movement of the transporting mechanism is automatically controlled so that the distance the garment is moved prior to each fastener attachment coincides precisely with the spacing desired between the leading edge of the garment and the first fastener-attachment, and the spacing desired between each subsequent fastener and the preceding fastener in a series of attachments.
