Abstract
Apparatus for the automatic infeed of a fibre sheet into a coiler comprises a smooth-surfaced transverse guide 6 to be placed at the delivery side of a pair of drawing rollers 1, 2. The guide 6 has an orifice 7 for gathering into a tuft the fibre sheet 3 coming from said pair of drawing rollers, a cylindrical outlet tube 8 extending said orifice 7, pneumatic means 18 for drawing the tuft into the outlet tube 8, and a pair of draw rolls 9 set at the downstream end of the outlet tube. The invention may be applied to the introduction of a fibre sheet into a coiler, the fibre sheet leaving the last pair of rollers of the drafting train of a machine.
