Abstract
A pneumatic cleaning apparatus arranged at the infeed table of a spinning machine, especially a drafting arrangement, wherein the infeed table possesses a number of sliver infeed locations. Each infeed location has operatively associated therewith a pair of rolls, forming a nip, for conveying in each case a sliver from a sliver supply, for instance a can. Each infeed location further has operatively associated therewith sliver guide elements arranged neighboring the related pair of rolls. At least the sliver guide elements are operatively associated with an air conducting means operatively connected with a negative pressure source.
Claims12
A pneumatic cleaning apparatus arranged at an infeed table of a spinning machine, especially a drafting arrangement, comprising:
- means defining a number of sliver infeed locations at the region of the infeed table;
- said means defining said number of sliver infeed locations comprising for each infeed location:
- a pair of cooperating rolls forming therebetween a nip for conveying a related sliver received from a sliver supply and having an inlet side and an outlet side;
- a pair of sliver guide elements associated with said pair of rolls, one sliver guide element of said pair being arranged at said inlet side and the other sliver guide element of said pair being arranged at said outlet side, each of said sliver guide elements defining an upwardly open guide groove and being spaced from said pair of rolls;
- air conducting means for conducting air at each of the sliver infeed locations;
- negative pressure source means operatively connected with said air conducting means;
- and at least said sliver guide elements being operatively associated with said air conducting means.

- sliver guide elements arranged neighboring said pair of rolls;
- sliver supply means for feeding a sliver to each sliver infeed location, said sliver supply means comprising at least one sliver can;
- air conducting means for conducting air at each of the sliver infeed locations in a direction substantially transversely to and across the path of travel of the sliver;
- negative pressure source means operatively connected with said air conducting means;
- and at least said sliver guide elements being operatively associated with said air conducting means.
