Abstract: In an apparatus on a carding machine for grinding a fiber processing clothing on a roller or a card flat, grinding equipment includes at least one grinding element and an infeed device serving to position the grinding element against the clothing. To permit reliable detection and monitoring of the contact between the at least one grinding element and the clothing in a simple manner, a structure-borne noise sensor is associated with the grinding equipment and an electronic evaluator is capable of determining from the structure-borne noise the intensity of the contact between the at least one grinding element and the clothing.

Abstract: An apparatus for depositing sliver in a coiler can includes a pair of cooperating pressure rolls; a coiler head rotating about a rotary axis and having a sliver inlet for receiving sliver from the rolls and a sliver outlet situated eccentrically with respect to the rotary axis for discharging sliver from the coiler head; a movable coiler can platform disposed underneath the coiler head for receiving an upwardly open coiler can thereon; and a severing device for severing the sliver at a location downstream of the rolls as viewed in a direction of sliver run. The position of the sliver outlet on its circular path, the position of the platform in its motion path and the running length of sliver are determined.

Abstract: A fiber processing machine includes a fiber processing roll carrying a first clothing on the surface thereof; and a countermember carrying a second clothing thereon. The first and second clothings cooperate with one another during operation of the fiber processing machine. A sensor determines a clearance between facing points of the first and second clothings. The sensor is mounted on the countermember and faces the first clothing when effecting measurement of the clearance.

Abstract: An apparatus for supplying sliver-filled coiler cans to and withdrawing empty coiler cans from an intake track of a sliver-consuming fiber processing machine has a plurality of serially-arranged coiler can changers. Each coiler can changer receives at least three coiler cans in a standby position, a working position and a removal position, respectively. The working positions of the coiler can changers form a row having opposite first and second sides. The standby positions and the removal positions of the coiler can changers are all situated at the first side of the row of working positions. Each coiler can charger further has a drive for simultaneously shifting the three coiler cans thereon to move a first of the three cans from the standby position to the working position and a second of the three cans from the working position to the removal position.

Abstract: An apparatus for measuring the quantity of fiber tufts during flight thereof, having an impact element provided with an impact face arranged in the flow path of the fiber tuft stream and being exposed for collision with the fiber tufts. The impact face is situated at an oblique angle to the flow direction of the fiber tufts. There is further provided a measuring element operatively connected to the impact element for generating signals representing stresses or excursions of the impact element derived from the collision of fiber tufts with the impact face. An electronic evaluating device is connected to the measuring element for receiving signals therefrom.

Abstract: A fiber bale opener includes an upwardly open bale supporting box having a bottom, bale supporting walls together surrounding the bottom for laterally supporting the fiber bale positioned on the bottom; a raising and lowering device connected to the bottom for vertically displacing the bottom and carrier elements for coupling the bottom to the raising and lowering device. The raising and lowering device is situated externally of and horizontally adjacent the box. There is further provided an opening device arranged for a back-and-forth travel above the box to remove fiber material from a top face of the fiber bale positioned on the bottom.

Abstract: A conveyor apparatus for advancing articles in a direction of conveyance, including a conveyor track on which the articles are supported; an endless driven conveyor element and an article carrier device including an article carrier element pivotally supported on the endless driven conveyor element. The article carrier element is adapted to engage and thus convey, or be disengaged from an article on the conveyor track. The article carrier element comprises a pivotal lever and a carrier lug formed on the pivotal lever. The latter has an activated pivotal position in which the carrier lug is adapted to be brought into and maintained in a force-transmitting engagement with one of the articles and a deactivated pivotal position in which the carrier lug is maintained disengaged from the articles. A force-exerting device urges the pivotal lever into the activated position. There is further provided a contact element on the pivotal lever downstream of the carrier lug as viewed in the direction of conveyance.

Abstract: An apparatus for generating measuring values representing the thickness of a coherent fiber material, includes an optical device having a light transmitter emitting a light beam and a light detector, an arrangement for guiding the fiber material between the light transmitter and the light detector and a device for processing signals generated by the light detector. The light detector comprises an image processing CCD member aligned with the light beam emitted by the light transmitter.

Abstract: 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.

Abstract: A carding machine has a main carding cylinder, an electromotor drivingly connected to the carding cylinder and a control device, including a memory, for controlling the rpm of the carding cyliner. The main carding cylinder has a starting phase during which the main carding cylinder is accelerated to a working rpm and a stopping phase during which the main carding cylinder is decelerated from a working rpm to standstill. The method of operating the carding machine includes the steps of storing in the memory material-specific sets of rpm values for the starting phase and sets of rpm values for the stopping phase; and controlling the rpm of the main carding cylinder in the starting and stopping phases by the control device in accordance with respective rpm values stored in the memory.
