In an apparatus for the fiber-sorting or fiber-selection of a fiber bundle comprising textile fibers, especially for combing, which is supplied by means of a supply device to a fiber-sorting device, especially a combing device, for removal of the combed fiber material at least one take-off device with a sliver-forming element is present, downstream of which is a drafting system. To increase productivity and obtain an improved combed sliver, downstream of the supply device there are at least two rotatably mounted rollers rotating rapidly without interruption, which are provided with the clamping devices for the fiber bundle, and between the sliver-forming element and the drafting system at least one conveyor element for a formed combed sliver is present.

In an apparatus at a spinning preparation machine, especially a card, having a clothed roller, at least machine element located opposite the roller clothing and spaced radially therefrom, and having two fixed lateral holding devices on which work elements are mounted, first and second measuring elements, connected to a control device are provided for detecting variables linked to the dimensions of the roller. The first measuring element comprises a temperature probe for the temperature of the roller surface. The second measuring element comprises a rotational speed sensor for the roller speed. To allow an actual carding nip to be determined, permitting a comparison with a preset carding nip, a third measuring element for the temperature of the holding devices is provided and the control device determines the actual spacing for the roller and the side panels.

Apparatus at a spinning preparation machine, especially a flat card, roller card, or the like, having a roller, e.g. a cylinder, which has a cylindrical clothed peripheral surface

An apparatus on a spinning preparation machine, especially a flat card, roller card, cleaner or the like, with a cooling system, a roller has a cylindrical peripheral surface and a casing opposite to and spaced from this peripheral surface, a carding region where carding work is carried out and heat is generated being present between the peripheral surface of the roller and a part of the casing. A cooling medium enters the interior void space of the roller, passes through and exits again. In order to reduce or avoid thermal expansion of the roller in a structurally simple manner, the cooling medium is a cooling gas, especially air, which is capable of absorbing heat in the interior void space of the roller and dissipating it from the interior void space of the roller.

A device is provided for separating out foreign particles and/or neps in a pre-carding zone and/or a post-carding zone of a carding machine having a carding cylinder. The device has at least two modules arranged opposite the carding cylinder in the pre-carding zone and/or the post-carding zone. Each module has a plurality of operating elements, the elements being arranged beside one another as seen in a circumferential direction of the cylinder. The operating elements are fixed carding elements, suctioning devices, and/or separating knives.

Multi-element separation modules for a fiber processing machine

A cylinder is provided for a spinning preparation machine. The cylinder has an outer shell having a hub at each end of the outer shell. A separate shaft journal is connected to each hub and the shaft journals are glued to the hubs.

Cylinder for spinning preparation machine

A device is provided for use in a carding machine having a roller with clothing, the device being for arranging opposite the clothing on the roller. The device has a flat bar, a clothing strip, and a rigid support element connected to the clothing strip and having fastening elements. The fastening elements engage the flat bar and exert pressure on the flat bar.

Device for attaching clothing to a flat bar

A flat bar is provided for use in a carding machine having a roller with clothing. The flat bar is for arranging opposite the clothing on the roller. The flat bar has a flat bar support body having a recess, a clothing support having a first side, the first side being positioned in the recess, flat bar clothing attached to a second side of the clothing support, the second side being opposite the first side, and at least one fastening element that secures the first side of the clothing support in the recess.

A device is provided for a spinning preparation machine for removing foreign particles, the machine having a rotating cylinder with ends. The device has a knife blade having a separation edge, the knife blade being arranged at an adjustable distance to and angled counter to a rotational direction of the cylinder; a suctioning chamber associated with the knife blade; a holding element to which the knife blade and the suctioning chamber are attached; and at least one adjusting element. The holding element, the knife blade and the suctioning chamber form a single adjustable unit. A position of the single adjustable unit relative to the cylinder is adjustable by adjusting the at least one adjusting element. The at least one adjusting element is located outside one of the ends of the cylinder in a longitudinal direction of the cylinder and in a region of the separation edge on the knife blade.

Device for spinning preparation

A flat bar assembly is provided for use with a carding machine having a carding cylinder, the carding cylinder having clothing.
