A travelling flats assembly for a carding machine comprises two end rollers; an endless flexible belt trained about the end rollers for a circulating travel, and a plurality of clothed flat bars arranged to be entrained by the endless flexible belt for circulating travel therewith. Each flat bar has a head forming a longitudinal end of the flat bar. There are further provided a stationary slide guide extending between the end rollers along the lower flight of the endless belt and slidably engaging and supporting the flat bars when entrained for travel by the lower flight; and a form-fitting connection for coupling the head of each flat bar to the outwardly-oriented face of the endless belt. The form-fitting connection allows an unobstructed freedom of motion of each flat bar in a direction generally perpendicularly away from and towards the outwardly-oriented belt face, whereby the flat bars are freely removable from and placed in an operative position onto the outwardly-oriented face of the upper flight of the endless belt.

A fiber processing line is formed of a plurality of fiber processing machines connected by a conveyor duct. A blower-conveyor is arranged for driving fiber tufts in an air stream through the conveyor duct. The blower-conveyor includes a discharge housing, a rotary impeller supported in the discharge housing; an inlet opening in the discharge housing for drawing the fiber material into the blower axially with respect to the impeller. The discharge housing includes a housing wall generally circumferentially surrounding the impeller and bounding a blower outlet which, similarly to the inlet, is connected to the duct. A waste separator is integrated in the blower-conveyor. The waste separator includes throughgoing openings in the housing wall for providing passages for waste from the fiber tufts upstream of the outlet opening as viewed in a direction of advance of the fiber tufts. The openings are sized to be sufficiently large to allow passage therethrough of waste larger than dust particles and sufficiently small to prevent passage of fiber tufts therethrough.

A card includes a main carding cylinder having a direction of rotation, a doffer cooperating with the main carding cylinder and a waste separator situated above the doffer and adjacent the main carding cylinder. The waste separator includes a knife blade situated close to the main carding cylinder and being oriented in a direction opposite the direction of rotation, a plate situated at a small radial distance from the main carding cylinder and having an edge defining a gap with the knife blade and a casing defining a suction chamber shrouding the gap. The casing and the knife blade are formed of a single-piece component.

A textile fiber processing machine includes a rotary cylinder having circumferential areas for engaging and circumferentially entraining fiber material introduced into the machine; and a waste grid situated adjacent to and radially spaced from, a circumferential portion of the cylinder. The waste grid allows waste from the fiber material to pass through. The waste grid has a plurality of grid bars supported parallel to one another. Adjoining grid bars define grid slots through which waste may pass. Each grid bar has a bar face oriented towards the cylinder and a free end portion. The bar faces are inclined towards the cylinder for abutting fiber material thrown towards the waste grid by the cylinder and for allowing waste material, after impingement thereon, to slide on the bar face towards and off the free end portion.

A sliver coiler including a rotary head supported in a machine frame. A device is provided for rotating the rotary head about its rotary axis. A pair of parallel extending cooperating feed rollers are rotatably supported in the rotary head for drawing sliver into the rotary head and discharging the sliver therefrom to deposit the sliver underneath the rotary head. A sliver coiler component surrounds the rotary head and has a circular track. During rotation, the rotary head turns relative to the sliver coiler component. A driving device provided for rotating the feed rollers includes a runner element which is rotatably supported by the rotary head and in contact with the circular track for running thereon during rotation of the rotary head, and a torque-transmitting mechanism for applying a driving torque from the runner element to the feed rollers.

A card has a frame including two parallel-spaced, rigidly supported side walls having lateral surfaces, a lickerin and a doffer disposed between the side walls and mounted on the lateral surfaces thereof; and carding organs situated between the lickerin and the doffer. At least some of these carding organs are, with their lateral end faces, disposed immediately adjacent the lateral surface of the respective side wall and are laterally mounted on the side walls.

An apparatus for breaking textile fiber bales includes at least two spiked breaker members rotated in the working direction for opening the bales at their underside; a stationary support rack for receiving thereon a plurality of bales juxtapositioned in the working direction; and an arrangement for moving the breaker members as a unit back and forth in the working direction underneath the support rack for opening the underside of the bales juxtapositioned on the support rack. The latter has a plurality of parallel-spaced support rods extending in the working direction above the breaker members.

Apparatus for breaking textile fiber bales

An apparatus for breaking textile fiber bales includes a plurality of spiked breaker members each rotated in a working direction and spaced from one another in the working direction and a support for receiving a series of juxtapositioned bales in the working direction above the breaker members for exposing the underside of the bales to the breaker members. The support comprises a flexible underlay which extends in the working direction for engaging face-to-face the underside of the bales and which is prevented from displacement in the working direction. An arrangement forms an upwardly open chamber of one part of the flexible underlay. The breaker members are accommodated in the chamber for engaging the underside of the bales situated at least in part within the outline of the chamber opening. The chamber and the breaker members are moved as a unit in the working direction along the bales.
