Patent number: 4970851Abstract: The combing machine comprises a detaching roll and an oscillating nipper unit comrising bottom and top nippers. The predetermined spacing for the oscillating nipper unit with respect to the detaching roll is adjustable, such predetermined spacing being the spacing between the front edge of a bottom-nipper plate and the nip location at the detaching roll when the oscillating nipper unit is in its front end position. A top comb is held in top-comb holders. Each top-comb holder on a top-comb bed is pivotably adjustable about an axis substantially parallel to the detaching roll, the top-comb bed being secured at the bottom nipper. Subsequent to an adjustment of the predetermined spacing, the top-comb holders are reset such that pins of the top comb are again located at the same predetermined distance from the detaching roll.Type: GrantFiled: August 4, 1989Date of Patent: November 20, 1990Assignee: Rieter Machine Works Ltd.Inventors: Hansulrich Eichenberger, Walter Ackeret
