Abstract:
The invention relates to a rotary plate of a spinning machine, in particular a section or a carding engine, for depositing a sliver in a canister, with a base body (2) and a band channel (3) arranged in the base body (2). In accordance with the invention, it is proposed that, when the rotary plate (1) is used as intended, the side of the rotary plate turned towards the rotary plate (1) features, at least partially, a coating (6) with a spatial configuration made of spherical, irregular elevations (11).
Abstract:
In a method of manufacturing a fibrous formed product, a mixture of fibers, including thick fibers and thin fibers, is prepared in order to form fibrous mats. The mixed fibers are supplied onto an outer peripheral surface of a roller. As the roller rotates, the mixed fibers are released from the roller and are thrown toward a fiber receiving surface. A fibrous mat is formed on the fiber receiving surface with a low-density layer next to the fiber receiving surface and a high-density layer on top of the low-density layer. Thick fibers mainly form the low-density layer and thin fibers mainly form the high-density layer. First and second fibrous mats are overlaid with one another such that their low-density layers oppose each other.
Abstract:
A sliver can with improved coupling elements for raising and lowering the bottom wall of the can during filling and otherwise manipulating the cans by can transport vehicles wherein the coupling elements are disposed within the laterally outermost contour of the can and are configured in conjunction with the width of associated guide slits in the side wall of the can to receive laterally movable can manipulators, e.g. on a can transport vehicle, for interlocking connection for transmitting upward movement of the manipulators to the bottom wall of the can and, optionally, lateral movement of the manipulators to the can for pushing and pulling movements.
Abstract:
A method of depositing a textile fiber sliver into flat sliver cans. The sliver is deposited in layers of loops similar in shape to cycloids produced under the action of an inner force effect of the sliver body in the flat sliver can. The force results from the combination of the rotary motion of an outlet aperture of the can coiler and of the mutual reversing rectilinear motion of the can coiler and of the flat sliver can in the direction of the longitudinal axis of the flat sliver can. The axis of rotation of the can coiler lies in the longitudinal axis of the flat sliver can. The width of the layers of the loops in the direction perpendicular to the longitudinal axis of the flat sliver can is inferior to the width of the inner space of the flat sliver can. Thus, a deflection is produced of the sliver loop towards the longitudinal walls of the flat sliver can at which there is a greater velocity of the mutual relative motion of the outlet aperture of the can coiler and of the flat sliver can.
