Abstract
A setting apparatus directs a reinforcing tape in a perpendicular direction to the path of movement of the fabric. It comprises a machine frame, a support plate, a setting punch and die, a reinforcing tape supply under the plate and tape feeding belt for feeding the tape which is automatically activated by the punch.
Claims20
Apparatus for setting snap fasteners onto a panel of fabric comprising:
- a. a machine frame,
- b. a horizontally disposed fabric support plate on the frame, the plate having a rear edge and accommodating lateral movement of the fabric in a direction parallel to the rear edge,
- c. an axially aligned upper punch and a lower die reciprocable in the frame and means for driving the punch down toward the die to meet the die approximately at the level of the plate and for raising the punch,
- d. feeding means in the frame for feeding fastener parts to the respective punch and die,
- e. a reinforcing tape supply under the plate and tape feeding means secured to the frame for feeding the end of the tape in a direction perpendicular to the rear edge to a working position in which the tape end overlies the lower die, the tape feeding means comprising a driven means mounted on the frame and having an axis parallel to the rear edge and pressure means mounted on the frame under the plate and pivotable about an axis also parallel to the rear edge, the pressure means adapted to swing about its pivot from a lower disengaged position to an upper engaged position whereat it cooperates with the driven means to move the tape, and
- f. severing means adjacent the die for severing the tape activated by the movement of the punch,
- whereby as the punch reciprocates once the tape is fed to the working position, the punch and die set a fastener on the fabric with the reinforcing tape disposed against the fabric between parts of the fastener and the severing means severs the tape.

Apparatus for setting snap fasteners onto a panel of fabric comprising:
- a. a machine frame,
- b. a horizontally disposed fabric support plate on the frame, the plate having a guide edge along the rear thereof for the positioning of the fabric,
- c. an axially aligned upper punch and a lower die reciprocable in the frame and means for driving the punch down toward the die to meet the die approximately at the level of the plate and for raising the punch,
- d. feeding means in the frame for feeding fastener parts to the respective punch and die, the feeding means being triggered by the raising of the punch,
- e. a reinforcing tape supply under the plate and tape feeding means secured to the frame for feeding the end of the tape in a direction perpendicular to the guide edge to a working position in which the tape end overlies the lower die, the tape feeding means comprising a pair of spaced rollers, a belt trained over the rollers, a pressure plate, spring means for urging the pressure plate toward the belt with the tape inbetween, and motor means operatively connected by connection means to one of the rollers to rotate it and drive the belt, and
- f. severing means secured to an element resiliently mounted on the lower die which is depressed as the punch comes down and severs the tape
- whereby as the punch reciprocates once the tape is fed to the working position, the punch and die set a fastener on the fabric with the reinforcing tape disposed against the fabric between parts of the fastener and the severing means severs the tape.

- e. a reinforcing tape supply under the plate and tape feeding means secured to the frame for feeding the end of the tape in a direction perpendicular to the guide edge to a working position in which the tape end overlies the lower die, the tape feeding means comprising parallel side plates journaling between them a drive roller, a pressure arm hinged to the side plates and amounting an idler roller for urging the tape against the drive roller when the arm is in a closed position, and motor means operatively connected by connection means to the drive roller to rotate it, and
- f. severing means secured to an element resiliently mounted on the lower die which is depressed as the die comes down and severs the tape,
- whereby as the punch reciprocates once the tape is fed to the working position, the punch and die set a fastener on the fabric with the reinforcing tape disposed against the fabric between parts of the fastener and the severing means severs the tape.
