Claims58
A process for making an endless belt of spliceless, Mobius strip construction which comprises the steps of:
- (a) wrapping an elongate strip of elastomeric material around two spaced apart building supports;
- (b) turning one end of said strip through 180 degrees;
- (c) joining the two ends of said strip, thereby forming a Mobius strip;
- (d) winding a continuous strength cord in the form of a helix around said Mobius strip and across the entire width thereof, thereby providing, in effect, two layers of cord winding;
- (e) winding at least one layer of an elastomeric material around said cord winding to provide an assembly;
- and
- (f) applying heat and pressure to said assembly to make said elastomeric material flowable and to surround and embed said cord.

- (b) turning one end of said strip through 180 degrees;
- (c) joining the two ends of said strip, thereby forming a Mobius strip;
- (d) winding a continuous strength cord in the form of a helix around said Mobius strip and across one-half the width thereof;
- (e) passing said cord-wound strip between means for squeezing said cord into approximately a single plane;
- (f) winding at least one layer of an elastomeric material around said cord winding to provide an assembly;
- and
- (g) applying heat and pressure to said assembly to make said elastomeric material flowable and to surround and embed said cord.

A process for making an endless belt of spliceless, Mobius strip construction which comprises the steps of:
- (a) wrapping an elongate strip of calendered cord fabric having a length equal to at least two times the length of the finished belt around two spaced apart building supports;
- (b) turning one end of said strip through 180 degrees;
- (c) joining said turned end to a portion of said strip to form a closed loop and continuing to wrap the remainder of said strip around the thus-formed loop;
- (d) winding at least one layer of an elastomeric material around said cord fabric to provide an assembly;
- and
- (e) applying heat and pressure to said assembly to make said elastomeric material flowable and to surround and embed said cord fabric.
A process for making an endless belt of spliceless, Mobius strip construction which comprises the steps of:
- (a) providing a warp consisting essentially of at least one continuous warp cord wrapped generally in the form of a helix of predetermined length and width and having a 180 degree turn at a given location along the length thereof;
- (b) winding at least one layer of an elastomeric material around said cord winding to provide an assembly;
- and,
- (c) applying heat and pressure to said assembly to make said elastomeric material flowable and to surround and embed said cord.
An endless belt of spliceless, Mobius strip construction having a 180 degree turn in the surfaces thereof for providing, in effect, one spliceless continuous surface and one spliceless continuous edge of twice the predetermined length of said belt comprising a continuous strength cord wrapped generally in the form of a helix of predetermined length and width and having a 180 degree turn along the length thereof, and an elastomeric material embedding and surrounding said cord.
