ABSTRACT:
A bearing device for use in textile drafting roller pairs for supporting the top roller of a drafting roller pair. The bearing device finds particular use with magnetic drafting rollers, but can be used with other types of roller configurations. The bearing device allows for the top roller to be selectively positioned with respect to the bottom roller in order to allow removal of the top roller and to prevent deformation of cots or aprons provided thereon during machine stoppage. A rotating debris excluding interface is also provided through interaction of the bearing device and the end of a roller. Handles are attached to the bearing device for allowing extraction of the top roller from a roller pair, and ribs may be provided on the bearing device or receptacle therefor to facilitate piecing up of a broken yarn. Related methods of use of the bearing device are also disclosed.
