Abstract
A carding machine in combination with an apparatus for charging a flat coiler can with sliver. The apparatus is disposed at the outlet of the carding machine and includes a rotary coiler head receiving sliver from the carding machine outlet and depositing the sliver in coils in the coiler can. The coiler can is reciprocated underneath the coiler head in a first direction for depositing sliver along a coiler can length extending parallel to the first direction. When charging of the coiler can is concluded, a device shifts the coiler head in a second direction over an additional coiler can for switching coiler cans from a full can to an empty can. A slack forming device for forming a slack in the sliver is arranged between the carding machine outlet and the coiler head.
Claims11
In a carding machine having an outlet, in combination with an apparatus for charging a flat coiler can with sliver;
- said apparatus being disposed at said outlet and comprising:
- a rotary coiler head receiving sliver from said outlet and depositing the sliver in coils in the coiler can;
- means for reciprocating the coiler can underneath said coiler head in a first direction for depositing sliver along a coiler can length extending parallel to said first direction;
- means for shifting said coiler head in a second direction over an additional coiler can for switching coiler cans from a full can to an empty can;
- and
- slack forming means for forming a slack in the sliver between said outlet of said carding machine and said coiler head,
- wherein the slack forming means forms the slack in the sliver such that the entire slack sliver is suspended by ends of the slack sliver.
A method of charging flat coiler cans with sliver outputted by a carding machine;
- the method comprising the following cyclical steps:
- (a) introducing sliver into a rotary coiler head from the carding machine;
- (b) depositing, by the rotating coiler head, sliver in coils in a first coiler can;
- (c) reciprocating the first coiler can underneath said coiler head in a first direction for depositing sliver along a coiler can length extending parallel to said first direction;
- (d) forming a slack in the sliver between an outlet of said carding machine and said coiler head;
- (e) when charging the first coiler can with sliver is concluded, shifting said coiler head in a second direction from above said first coiler can over a second coiler can;
- (f) upon completion of step (e), depositing sliver in the second coiler can situated adjacent said first coiler can;
- and
- (g) after completion of step (e), replacing said first coiler can with a third coiler can,
- wherein the slack is formed in the sliver such that the entire slack sliver is suspended by ends of the slack sliver.
