Abstract

The use of metal bands for pin feeding requires a joint capable of flexing to the radius of the drive wheel twice each revolution and pin connections which are unaffected by the flexing. A butt-welded band must be thick enough to provide a strong, easily made weld which in turn requires a large diameter drive wheel to minimize the stress imposed during flexing. Also, a portion of the band around each pin must be relieved to prevent high stresses in the area during flexing.

Pin-Feeding With Bands

The use of metal bands for pin feeding requires a joint capable of flexing to the radius of the drive wheel twice each revolution and pin connections which are unaffected by the flexing. A butt-welded band must be thick enough to provide a strong, easily made weld which in turn requires a large diameter drive wheel to minimize the stress imposed during flexing. Also, a portion of the band around each pin must be relieved to prevent high stresses in the area during flexing.

With the pins P connected to the band and the ends of the band joined under one of the pins, it is possible to use a thinner band and as a result a smaller diameter drive wheel without need for relieving any areas around the pin. All flexing of the band takes place outside of the rivet area with equal stresses throughout. Registration of the band to the drive wheel is accomplished with two lateral pins R in each block which mesh with slots in flanges attached to the drive wheel. By feathering the ends of the bands, as at F, a clean joint is made.
