  • Publication number: 20220251737
    Abstract: The invention relates to a card with a device for recognizing interfering particles, in particular trash parts, neps, shell neps, thick spots and/or foreign parts in a carded fibre web. The device comprises at least one sensor stationarily disposed in a web guiding element, which is disposed at the transition from a doffer to a stripper roll. The at least one sensor detects the fibre web on the doffer.

  • Patent number: 8132297
    Abstract: In an apparatus on a carding machine having a cylinder and at least one doffer, in which the cylinder and the doffer each have an all-steel clothing having saw teeth, the clothing on the cylinder and the clothing on the doffer each have a point density per square inch (ppsi). For achieving increased production rate with the same quality or improved quality with the same production rate, the clothing on the doffer has a point density of at least 400 ppsi, and the ratio between the point density of the clothing of the cylinder and the point density of the clothing of the doffer influences the proportion of the fiber mass that is transferred from the cylinder to the doffer per revolution of the cylinder in the sense of a higher production rate or higher quality of the card.

  • Publication number: 20090158558
    Abstract: A saw-tooth clothing for rollers and/or cylinders of flat cards or roller cards has a foot region and an adjoining tooth region (blade) in which teeth have been formed by cutting, with a tooth front a tooth back and two side flanks, wherein between the tooth back and the tooth front of two adjacent teeth there is a gullet and the teeth consist of at least two portions, with a first portion, forming a technologically effective region. In order to provide a clothing that retains a high level of aggressiveness over its lifetime, the first portion of the tooth front is convex or approximately convex in the direction of movement of the clothing.

  • Publication number: 20040239018
    Abstract: The aim of the invention is to configure a device for winding and unwinding partly rolled products, in a way that ensures the smallest possible accumulation of scrap. To achieve this, a roller (20, 20′, 20″) whose position is controlled and which runs on the periphery of the coil is used during the transfer of the coils from the winding station to the unwinding station. The vertical adjustment of said roller ensures that the coil is completely unwound, even with a diminishing coil diameter.

  • Patent number: 6408488
    Abstract: A fiber processing machine includes a roll having a circumferential surface provided with a first clothing having clothing points; a counter member having a surface provided with a second clothing cooperating with the first clothing and having clothing points; and a device for setting a clearance between the clothing points of the first and second clothings. The device includes an arrangement for approaching the roll and the counter member to one another until the clothing points of the first and second clothings contact and for moving away the roll and the counter member from one another until the clothing points of the first and second clothings assume a desired clearance. The device further has an arrangement for emitting a signal when the clothing points of the first and second clothings contact one another.
