Abstract:
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.
Abstract:
In an apparatus at a carding machine for grinding a clothing drawn onto a rotating roller, having a carrying device with at least one grinding element and an advancing device serving to set the grinding element against the clothing, wherein the apparatus comprises a biasing device serving for automatically continuing to push forward the grinding element in a contact-making direction during the grinding procedure, the carrying device is attached to the carding machine. In order to make it possible, by simple means, to shorten the time until service-readiness carrying elements adjusted in respect of the spacing b relative to the roller are utilised for adjustment of the biasing device.

Abstract:
In an apparatus at a carding machine having a web removal and sliver formation device, there are provided, following on from the web removal device, a web funnel and a pair of draw-off rollers, which are arranged to pivot together with a rotary mounting. In order to provide an apparatus which is dimensionally stable and which facilitates servicing work, the web-guiding element, on the one hand, and the web funnel together with the pair of draw-off rollers, on the other hand, are arranged to pivot separately about the rotary mounting and are connected to one another by means of a locking and unlocking device.

Abstract:
A carding machine includes a main carding cylinder having a cylindrical surface carrying a cylinder clothing; a cover arrangement extending along a part of the cylindrical surface at a clearance therefrom to define a space between the cylinder clothing and the cover arrangement; a first opening provided in the cover arrangement and communicating with the space between the cylinder clothing and the cover arrangement; and a device for generating a pressurized air stream. The device communicates with the first opening for introducing the pressurized air stream through the first opening into the space between the cylinder clothing and the cover arrangement to impinge upon the cylinder clothing carrying fiber material thereon. A second opening which is provided in the cover arrangement communicates with the space between the cylinder clothing and the cover arrangement for removing the pressurized air stream, laden with waste material separated from the fiber material.
Abstract:
A carding machine includes a machine frame; a fiber processing roll carrying a roll clothing and having a rotary axis; and a stationary carding segment including a carrier mounted on the machine frame; and two carding elements affixed to the carrier and arranged serially as viewed circumferentially of the roll. Each carding element has an element clothing for cooperating with the roll clothing. The carding segment further has a mechanism for turning the carding elements as a unit about a turning axis extending parallel to the rotary axis of the roll for adjusting a distance of the element clothings from the roll clothing.
