Abstract
To provide a twisting apparatus in which one of a pair of twisting rollers t1 and t2 is a hollow rubber roller t1, while the other is a hard cylindrical roller t2 in which a rubber band t16 is installed. Twisting efficiency is improved compared to the conventional twisting roller both comprising hollow rubber rollers. Thus, by applying the present invention to a spinning apparatus for manufacturing spun yarn from a fiber set, the spinning speed of the spun yarn can be increased and the spinning range extended.
Claims6
A twisting apparatus for twisting a fiber set including a pair of twisting rollers mounted for rotation on crossed shafts, said rollers having mutually cooperating circumferential contact regions for gripping and twisting said fiber set wherein one of said pair of twisting rollers contains a contact region defined by a hollow rubber roller and the other of said pair of twisting rollers contains a contact region defined by a hard, substantially solid cylindrical base and a rubber band circumferentially surrounding said base for engagement with the contact region of said one twisting roller.
A twisting apparatus for twisting a fiber set including a pair of twisting rollers mounted for rotation on crossed shafts, said rollers having mutually cooperating circumferential contact regions for gripping and twisting said fiber set wherein one of said pair of twisting rollers contains a contact region defined by a hollow rubber roller and the other of said pair of twisting rollers comprises a composite body formed of substantially rigid members and a contact region defined by a hard, abrasion-resistant cylinder supported by said rigid members.
