Abstract
Waste fabric and lint generated by the cutter knives of a sewing machine are removed as generated by a collection box, the top edges of which are shaped to conform to the contour of a sewing machine frame in a location immediately beneath the cutter knives. The collection box is connected to a source of suction in a waste removal system.
Claims9
A waste and lint collector for collecting and conveying waste and lint away from a sewing machine having needles for sewing fabric and cutter knives for trimming away excess fabric, said waste and lint collector comprising an open top collection box communicatively connected with an inlet end of a waste conduit, said collection box of rectangular cross-sectional configuration and comprising a front wall, a rear wall and side walls, the tops of said walls defining an edge about the open top of the collector, said edge being shaped to sealingly fit against the frame of the sewing machine and to position the open top of the collection box in an operative position immediately beneath the cutter knives, and means for inducing a flow of air into the collection box from the area of the cutter knives, whereby trimmed fabric and lint is drawn into the collector box as it is generated and before it escapes into the atmosphere.
A method of collecting and conveying trimmed fabric edges and lint away from a sewing machine as the trimmed fabric edges and lint are generated by cutter knives on the sewing machine, said method comprising the steps of:
- (a) providing a collection box having an open top and a front wall, rear wall and side walls, the tops of said walls defining an edge about the open top,
- (b) shaping the edge to conform to the configuration of the sewing machine sufficiently to position the open top of the collection box to sealingly fit against the portion of said frame immediately beneath the cutter knives,
- (c) providing a pneumatically operable waste removal system, including a main line,
- (d) generating a suction current through the main line, and
- (e) connecting the main line to a waste conduit communicatively connected to the collection box;
- whereby air is drawn from the area of the cutter knives carrying with it lint and trimmed fabric into the collection box and conveying the lint and trimmed fabric into the waste removal system.
