Flexible Channel for Web Guiding

Shown is a channel 10 wrapped about a curved bearing surface 12. The channel 10 can be used to guide a web 11, such as magnetic tape, along a curved path adjacent the curved bearing 12.

The channel 10 is made from a flexible material and contains alternate long teeth 14 and short teeth 16 along its sides. Cuts between the teeth assist the wrapping of the channel 10 about curved bearing 12.

Further, during threading of tape 11 through the channel 10, air is blown with the tape as the tape is pushed through the channel. The difference in height between the tall teeth 14 and short teeth 16 provide an air vent out the sides of the channel 10. This venting of air tends to maintain the tape 11 halfway between the bottom of the channel and the bearing surface during the threading operation. However, if the tape 11 were to touch the bottom of the channel 10, ridges 18 are provided in the channel to prevent the tape from sticking to the bottom of the channel due to electrostatic attraction.
