ABSTRACT:
A sliver opening and fiber feeding device for opening a sliver into individual fibers and feeding the individual fibers to the rotor of an open end spinning machine is provided with a polytetrafluoroethylene coating for the interior surface of the housing of the sliver feeding and opening device, in particular, the trash discharge passage. The polytetrafluoroethylene coating advantageously has a relatively low co-efficient of friction to thereby reduce the affinity of sticky material, which may be present in the sliver due to the presence of insect residue or the like, to stick to the interior surfaces of the device. The polytetrafluoroethylene coating is included on an insert element mounted in the discharge passage, with the insert element being capable of being retrofitted in an existing sliver opening and fiber feeding device.
