Abstract
A combination of a sliver intake assembly for guiding and introducing simultaneously a plurality of slivers into a drawing frame and a suction assembly for removing waste, such as dust or fiber fly. The combination includes an emplacement situated below the sliver intake assembly for accommodating a plurality of coiler cans from which slivers are withdrawn by the sliver intake assembly. The suction assembly has a suction duct which extends along the sliver intake assembly in a region thereof for drawing waste thereinto by vacuum.
Claims18
A combination of a sliver intake assembly for guiding and introducing simultaneously a plurality of slivers into a drawing frame and a suction assembly for removing waste;
- said slivers having a direction of advance through said sliver intake assembly;
- said sliver intake assembly comprising a plurality of rolls spaced in said direction of advance for guiding said slivers;
- said combination comprising
- (a) an emplacement situated below said sliver intake assembly for accommodating a plurality of coiler cans from which slivers are withdrawn by said sliver intake assembly;
- (b) a suction duct forming part of said suction assembly and extending along said sliver intake assembly in a region thereof for drawing waste thereinto by vacuum;
- and
- (c) a common air guide extending along said sliver intake assembly over said plurality of rolls;
- said common air guide forming part of said suction assembly and being coupled to said suction duct for guiding air into said suction duct.
A combination of a sliver intake assembly for guiding and introducing simultaneously a plurality of slivers into a drawing frame and a suction assembly for removing waste;
- said combination comprising
- (a) an emplacement situated below said sliver intake assembly for accommodating a plurality of coiler cans from which slivers are withdrawn by said sliver intake assembly;
- (b) a suction duct forming part of said suction assembly and extending above and along said sliver intake assembly;
- said suction duct having air intake apertures along said sliver intake assembly for providing passage of air into said suction duct;
- (c) a hood forming part of said suction assembly and extending along and over said sliver intake assembly;
- said hood having an operative position in which said hood defines a downwardly open space;
- said air intake apertures being situated in said space;
- and
- (d) means for coupling said suction duct to a vacuum source for generating an air current in said suction duct in a flow direction.
