摘要:
A quickly-coupled delivery device for automatic machines for applying buttons and other metal fittings on a support comprises a hopper (4) and a rotary bell (5) which is rotatively driven by a driving shaft (10), in turn driven by a belt transmission (11,12), provided with a quick coupling system (14,16) for operating the rotary bell, and adapted to allow the belt transmission to be received inside the body of the machine. The inventive device, owing to its quick coupling system arranged on the bell driving shaft (17), so as to allow the drive belts (11) to be brought inside the body of the machine, facilitates and simplifies the delivery device opening operations; moreover, the quick coupling of the rotary bell (5) on the driving shaft (10) facilitates the empting operations for removing from the bell the metal fittings.

Die Erfindung betrifft eine Vorrichtung zum drehwinkelgerechten Ansetzen von Knöpfen, Nieten oder dergleichen, insbesondere an Kleidungsstücke, durch Drehen des im Oberwerkzeug angeordneten, mit einem Index (65) ausgestatteten Knopfteiles (63) mittels einer Oberwerkzeug-Drehzange (24, 75); zur Erzielung einer baulich und funktionell vorteilhaften Lösung schlägt sie vor, daß die Oberwerkzeug-Drehzange (24, 75) unter Zwischenschaltung einer Reibungskupplung kontinuierlich angetrieben und in unterschiedlichen Drehwinkelstellungen durch Anschläge (58) stoppbar ist.
摘要:
A method and apparatus for protecting a horizontally reciprocable light projector (8) from collision with a vertically reciprocable punch (1) of a button setting machine, wherein a lost motion mechanism (21) is provided for producing a delay between retracting movement of the light projector (8) and the downward movement of the punch (1) to such an extent that the light projector (8) is retracted from the vertical path of movement of the punch (1) before the punch (1) starts moving downward. The lost motion mechanism is composed of a shaft (16) having an annular actuating flange (18), and a cylinder member (17) slidably receiving therein the shaft (16). The actuating flange (18) is normally separated from the cylinder member (17) and engageable with the cylinder member (17) to lower the punch (1) when the light projector (8) is retracted from the vertical path of movement of the punch (1).

A foot-operated press (10) includes a ratchet mechanism (13) operatively connecting a foot pedal (12) and a punch (18) of the press (10) for preventing backward movement of the foot pedal (12) until after the punch has fully been lowered to ensure that a pair of fastener elements can be assembled together in properly clinched condition, with a garment fabric disposed between the two fastener elements.
摘要:
A method and apparatus for applying a fastener having a body member (12) and a rivet member (14) to a compliant sheet material (18) includes anti-pucker apertured member (48) having an opening (52) therein coaxially aligned with first and second tool members (42,40). The inner peripheral wall (54) of the apertured member is of substantially the same cross-sectional configuration as the body of the fastener, the opening of the apertured member being of a size large enough to accept the body of the fastener with the upper portion of the inner peripheral wall of the opening (52) adapted to cooperate with the outer peripheral surface (32) of the body of the fastener to capture the material therebetween the stretch the material taut over the bottom end (34) of the body of the fastener such that a post member (16) can pierce the material and be received within a recess (20) in the bottom end of the body without wrinkling or puckering the material.
