Abstract: A device for filling a series of non-circular cans, which are disposed on a conveyor, with sliver from a sliver producing textile machine. A coiler for delivering sliver to the cans is supported on an ancillary frame which is, in turn, supported for movement on a main frame. The cans are supported on the conveyor that moves past the coiler in a direction perpendicular to the long axis direction of the respective cans. A double acting piston cylinder arrangement moves the coiler and a cover over the can in which the coiler is disposed along the path of movement of the conveyor for moving the coiler over the can to be filled. The cover and can coiler together are moveable along the long axis plane of each of the cans by a drive for moving the coiler to deliver the sliver into the can.

Abstract: A system for winding filamentary material around a cone. The system includes: a drive ring for rotating the cone and a lateral ring for supporting the cone. The lateral ring is rotatable with respect to the drive ring. The angular velocity of the cone is controlled by controlling the rotation of the lateral ring responsive to the tension of the filimentary material and/or responsive to the diameter of the cone.

Abstract: A fiber opening device of the spinning unit of an openend rotor spinning machine, for avoiding misalignments in the connection between the front end of the sucking tube of a travelling automatic service unit and the inlet port of the spinning unit, in order to prevent false air from being sucked in at this contact point. According to the invention, a sucking tube is provided with a self-adjustable sealing head having a front sealing surface to be fitted onto the front wall of the spinning unit. In the inner space of the sealing head a partially spherical concave surface fitted onto a mating, partially spherical convex surface provided at the end of the said sucking tube.
