Abstract
The process for the positioning of a fiber sliver end is characterized in that in the stopped position of the flat can a drafting point is formed in the fiber sliver between the pair of calendar rollers and the sliver guiding channel and in that subsequent displacement of the flat can into a transfer position causes the fiber sliver to be severed at the drafting point and to be pulled out of the rotary plate, so that it is positioned with a constant length on the flat can.
Claims8
A process for the positioning of a fiber sliver of a filled flat can, wherein the fiber sliver is conveyed to the flat can by a pair of calendar rollers through a sliver guiding channel of a rotary plate and deposited cycloidally in the flat can, said process comprising:
- stopping fiber sliver delivery for can replacement;
- bringing the flat can to a stopped position;
- stopping the rotary plate so that an outlet of the rotary plate is in a predetermined known position relative to the flat can;
- with the flat can in its stopped position, defining a drafting point in the fiber sliver with a drafting device between the pair of calendar rollers and the sliver guiding channel;
- and
- severing the fiber sliver at the drafting point by displacing the flat can with a displacing device from its stopped position after defining the drafting point, the severed sliver end thereby being pulled out of the sliver guiding channel with a constant length.
