Method and apparatus for cleaning fiber material at a spinning preparation machine

Abstract

In a method at a spinning preparation machine, for example a cleaner, opener, carding machine or the like, for cleaning fibre material, especially cotton, an examination of the nature of the trash iscarried out, which examination is used for adjustment of at least one adjustable cleaning element, for example a separating blade, cleaning grid or the like. In order to make possible improved and undisrupted production by simple means, the optimum adjustment of the at least one cleaning element for a specific fibre batch is stored in a memory of an electronic control and regulation device and, when the same fibre batch is processed again, the optimum adjustment of the cleaning element is implemented automatically.

Description

technical field [0001] The invention relates to a method for cleaning fibrous material, in particular cotton, on spinning preparation machines such as cleaning machines, uncoilers, cards, etc., wherein a check of the nature of the waste is carried out for adjusting at least one adjustable cleaning element, such as separating Blades, cleaning grids, etc., the invention includes apparatus for implementing the method. Background technique [0002] In fact, in textile cleaning machines, for example, especially in pre-cleaning machines, the degree of cleaning is basically adjusted by means of manually adjustable grids. This means that the amount and nature of waste removal is related to the location of the grid. However, this also means that in case the adjustment is incorrect, an excess of good material is often removed, or the existing cleaning potential is not fully utilized. This is especially a problem when the material being processed is changed frequently. [0003] In a...
