Abstract
A system for charging a coiler can of elongated horizontal cross section with sliver obtained from a sliver producing fiber processing machine includes a stationarily supported rotary coiler head discharging sliver in coils; a sled disposed underneath the coiler head for receiving a coiler can in an upright orientation; and a sled-reciprocating device for imparting a rapid back-and-forth motion to the sled during discharge of sliver from the coiler head to effect a deposition of sliver coils into the coiler can along a length thereof.
Claims11
A combination of a high-production rate sliver producing machine with a system for charging a coiler can of elongated horizontal cross section with sliver obtained from the sliver producing machine,
- said sliver producing machine comprising a stationarily supported rotary coiler head having a diameter generally corresponding to the width of said coiler can for discharging sliver in coils;
- said system comprising
- (a) a coiler can having two opposite first sides and two opposite second sides oriented generally perpendicularly to said first sides;
- said coiler can having an elongated horizontal cross-sectional outline having a length corresponding to a distance between said second sides and a width corresponding to a distance between said first sides;
- said length being greater than said width;
- (b) a sled disposed underneath said coiler head;
- said sled having an upper supporting surface for accommodating said coiler can in a standing position thereon, whereby said sled provides a vertical support for said coiler can;
- and
- (c) sled-reciprocating means for imparting a sufficiently rapid back-and-forth motion to said sled parallel to the length of the coiler can to effect a deposition of sliver coils into the coiler can along a length thereof during discharge of sliver from said sliver producing fiber processing machine at a sliver discharge speed in an order of magnitude of 1,000 m/min.
