Abstract

Initially, a polyester film is threaded up a multispindle winder as shown in Fig. 1. Approximately the first 300 feet of a new supply spool are to be scrapped, and anything less than 500 feet on the end of a used supply spool is likewise to be scrapped. An idler is used to establish a film path tangent to the cartridge spool diameter at about a 10 degree angle. The same idler is used in conjunction with a pressure roll as a drive element to scrap and clamp the film. As shown in Fig. 2, the pressure roll is essentially a combination of three bearing housings, a fixed shaft and two rotating shafts coupled by gears and driven by a motor coupled to the end of the driver shaft and fixed to the mounting plate. Bearing housing 12 is fixed to the mounting plate 20. The driver shaft 19 is mounted in bearings within bearing housing 12.

One-Direction, Non-Slip Pressure Roll Drive and Clamp

Initially, a polyester film is threaded up a multispindle winder as shown in Fig. 1. Approximately the first 300 feet of a new supply spool are to be scrapped, and anything less than 500 feet on the end of a used supply spool is likewise to be scrapped. An idler is used to establish a film path tangent to the cartridge spool diameter at about a 10 degree angle. The same idler is used in conjunction with a pressure roll as a drive element to scrap and clamp the film. As shown in Fig. 2, the pressure roll is essentially a combination of three bearing housings, a fixed shaft and two rotating shafts coupled by gears and driven by a motor coupled to the end of the driver shaft and fixed to the mounting plate. Bearing housing 12 is fixed to the mounting plate 20. The driver shaft 19 is mounted in bearings within bearing housing 12. The outside diameter of bearing housing 12 contains bearings which retain a stationary shaft about which bearing housing 14 rotates. An extension of bearing housing 14 contains bearing housing 16. Within bearing housing 16 is the driven shaft 21 mounted in a one-direction roller clutch 22.

A cylinder (not shown) is coupled to bearing housing 14 and, when activated, bearing housing 14 pivots until the pressure roll comes in contact with the idler. The film is now clamped. When the motor is activated, the pressure roll is turned by the gears 27, 28, and the pressure in turn...
