Abstract
An apparatus for precisely orienting working elements, such as carding elements, to a rotating fiber-opening roller, such as a licker-in, with regard to both distancing and centering without necessitating complex adjustment mechanisms. The working element is precisely positioned by virtue of respective abutting engagement surfaces of the axle boxes or roller retainers and the carrier of the working elements.
Claims31
An apparatus comprising:
- a fiber-opening roller extending along a longitudinal axis, said roller having an exterior periphery;
- a plurality of roller retainers for supporting said roller at spaced locations for rotation around said longitudinal axis of said roller;
- a working element;
- a positioning arrangement for setting said working element at a predeterminate position with respect to said roller;
- said positioning arrangement comprising a plurality of spacers for positioning said working element a predeterminate distance from said exterior periphery of said roller;
- and
- said plurality of spacers being longitudinally spaced apart and each of said spacers being located between a respective roller retainer and a respective portion of said working element for ensuring precise radial and pivotal orientation of said working element relative to said fiber-opening roller.

An apparatus comprising:
- a fiber-opening roller extending along a longitudinal axis, said roller having an exterior periphery;
- a plurality of roller retainers for supporting said roller at spaced locations for rotation around said longitudinal axis of said roller and at least one abutting engagement surface of each of said roller retainers fixed with respect to each respective roller retainer;
- a working element and at least one abutting engagement surface of said working element fixed with respect to said working element;
- a positioning arrangement for setting said working element at a predeterminate fixed position with respect to said roller against radial and pivotal adjustability of said working element with respect to said roller, by affixation of a first engagement surface with a second engagement surface, said first engagement surface comprising either one of said abutting engagement surfaces of said working element or said abutting engagement surface of a respective roller retainer and said second engagement surface comprising an abutting engagement surface fixed with respect to the other of said working element and a respective roller retainer.
