Abstract
The detaching roller aggregate comprises two pairs of cylinders each consisting of a detaching roller and a printing cylinder which are pressed against each other by means of a contact pressure device. The contact pressure device is arranged in such a way as to press the two cylinders of the second pair against each other with a larger force than the force pressing the two cylinders of the first pair together. The ratio of the two forces may be approximately 1.2:1 to 2:1. Due to the larger force with which the cylinders of the second pair are pressed against each other, a more even top fleece is produced, in particular during the combing of relatively long fibers and/or at high processing speeds.
Claims15
A detaching roller aggregate for a combing machine comprising
- a first pair of cylinders including a detaching roller and a printing cylinder for receiving a fiber tuft from a combing machine for attachment to a previously formed fleece, said detaching roller being rotatable in a pilgrim step movement;
- a second pair of cylinders including a second detaching roller and a second printing cylinder for passage of the fleece therebetween, said second detaching roller being rotatable in a pilgrim step movement;
- and
- means for pressing said cylinders of said first pair together under a first force against each other and said cylinders of said second pair together under a second force against each other larger than said first force.
In combination,
- a combing head having an oscillating nipper;
- and
- a detaching roller aggregate adjacent said nipper to detach fiber tufts therefrom, said aggregate having two pairs of parallel cylinders for receiving fiber therebetween and means for pressing said cylinders of an upstream pair of said paris together under a first force and said cylinders of a downstream pair of said pairs together under a second force larger than said first force.
