Abstract

1506396 Measuring thickness of slivers JAMES MACKIE & SONS Ltd 27 Aug 1975 [27 Aug 1974] 37439/74 Heading G1M [Also in Division D1] The thickness of a sliver is measured by passing it between a pair of co-operating rollers, roller 1 being mounted for rotation in a fixed position and roller 2 being movable towards and away from roller 1 in accordance with the thickness of the sliver, roller 2 being loaded against fixed roller 1 by a pneumatic cylinder 18. Preferably roller 2 is mounted on arm 8 of a bell crank type lever and the loading force is applied via chain 21 to a second arm 12. A third arm 15 is connected through a link assembly 11 for positioning the pins on a memory wheel (not shown). The draft of the sliver is increased over the thicker regions and decreased over the thinner regions. A relieving pressure regulator 26 allows air in the cylinder to exhaust should an excessively thick piece of sliver pass between rollers 1, 2. The air supply to the cylinder is cut off by a solenoid valve (not shown) when the sliver is stationary to prevent its over-compression.
