Abstract

A machine for the attachment of buttons, rivets or the like on clothing pieces, the lower parts of which are fed via rails from a magazine laterally oriented up to the vicinity of the attachment position and from there are transferred into the attachment position. The rail which feeds the bottom parts in the edgewise position exits at an angle which is offset by about 90 degrees relative to the attachment position. Between the exit position and the attachment position there extends a circular arc-shaped slide surface starting tangentially from the exit area and running approximately tangentially into the attachment position. A rotatable ring section runs on the slide surface. The ring section, which is equipped on its front end with a reception pocket, transfers respectively one lower part into the attachment position and during its movement its ring-narrow-edge closes the exit of the feed rail.

Claims8

Dependent claims

In a machine for the attachment of fasteners on clothing pieces, the fasteners comprising upper parts and lower parts adapted to be attached together by upper and lower tool stamps on the clothing pieces at an attachment position, with a magazine adapted to store the parts of the fasteners and being oriented laterally relative to the attachment position, a feed rail extending from the magazine up to a vicinity of the attachment position feeds the lower parts to this vicinity, and swingable means for transferring the lower parts from this vicinity into the attachment position, the improvement wherein

said feed rail has an exit mouth at said vicinity and constitutes means for feeding the lower parts to said exit mouth in a substantially edgewise-upright position, said exit mouth is located at an angle offset by about 90 degrees relative to the attachment position,
a slide surface extends from said exit mouth up to the attachment position, said slide surface is circularly arc-shaped, beginning tangentially from said exit mouth and running substantially tangentially into the attachment position,
a rotatable ring section having a bearing surface rotatably running on said slide surface, said ring section on a front end thereof forms a reception pocket constituting means for receiving one of said lower parts, respectively, at said exit mouth with said one lower part substantially oriented in the edgewise-upright position and positioned against said slide surface and running against said slide surface in said reception pocket during rotation of said ring section on said slide surface, directly delivering and transferring said one lower part into the attachment position and simultaneously turning said one lower part via said slide surface from said edgewise-upright position substantially into a horizontal position at the attachment position, and
said ring section on said said front end has a narrow edge, the latter during the rotatable running of said ring section on said slide surface being positioned closingly against the exit mouth of the feed rail.
