With Fiber Sampling Patents (Class 19/297)
  • Patent number: 5974629
    Abstract: A method of measuring fiber material while being processed by fiber processing components of a carding machine, includes the following steps: measuring fiber length and nep number at an outlet of the carding machine; applying measured values of the fiber length and nep number to a control and regulating device; forming, in the control and regulating device, optimized machine setting data for the fiber length and the nep number; and applying the optimized machine setting data to at least one of the fiber processing components affecting fiber length and nep number.

  • Patent number: 5671495
    Abstract: A recyclable shoe midsole cloth is made from a recycled waste fabric material or a recycled rejected fabric product. The recycled material or product is processed such that the threads making up the recycled material or product are rehabilitated to become raw cotton materials, which are then processed to become the recyclable shoe midsole cloth.

  • Patent number: 5068947
    Abstract: A separation apparatus for fiber webs (6) with parallelized fiber positions wound on a processing drum (4) includes an arm (1) rocking relative to the processing drum, the arm carrying a separation comb (13). The arm and its separation comb (13) are mounted for movement along and controlled by the shape of a separation cam (3) implementing the separation of the fiber web (6) wound on the processing drum (4) at a specified site and the unwinding of the separated fiber web from the processing drum (4) by the free end of the fiber web (6) along a generatrix of the surface of the processing drum (4).

  • Patent number: 4953265
    Abstract: For detecting neps in a textile fiber fleece band transported along a transporting path through a carding machine a detecting device comprises a mechanism for illuminating the fiber fleece band on at least one area located on the transporting path. Imaging optics project an image of this illuminated area onto the surface of one of a plurality of photo sensor elements. The area projected onto each one of the photo sensor elements substantially corresponds to the size of the neps to be detected. The photo sensor elements are connected to evaluation circuits for evaluating light intensity variations caused by neps passing the illuminated area.

  • Patent number: 4399590
    Abstract: A method of, and apparatus for, checking a plant for blending textile staple fibres of different types, which are supplied by fibre metering units. The supply of fibres to the storage device is interrupted during repeated time intervals. According to the invention the fibres supplied by an individually operated fibre metering unit, supplying a constant quantity, during part time intervals within the time intervals are transported to a quantity measuring device and are measured.The present invention permits very reliable and precise checking of the fibre quantities supplied by the fibre metering units in such a manner that a desired blending proportion can be maintained precisely. The machines fed from the storage device can be maintained operating during the checking periods, i.e. at all times.
