Abstract: 561,447. Lap-forming apparatus. MACKIE & SONS, Ltd., J., and MACKIE, J. P. Feb. 1, 1943, No. 1658. [Class 120 (i)] In a lap - forming apparatus in which the doffing or ejection of a completed roll and the starting of the winding of a fresh roll are effected automatically and in which the roll is supported and rotated by three continuously driven rollers, one above and two below the roll, the completed roll is caused to fall and move forwardly out of the machine by the sudden downward displacement of the front lower roller and under the resultant pressure exerted upon the roll by the continuously rotating rollers. As shown, the front lower roller 10 is carried by a short spindle 29 in a frame 30 pivoted on the shaft 9 of the rear lower roller 11 and provided with a counterweight 32 and during formation of the roll, the frame is held up by a projection 130 thereon engaging a spring- pressed latch lever 25 pivoted at 26. The rollers are driven, the upper roller is mounted, and the new roll is started as described in Specification 554,394, and when the roll is completed a projection 21, on the carriage 16 of the upper pressure roller 12, engages an adjustable stop 22 on the vertically movable rod 23 and raises it, a lug 24 at the bottom of the rod then engaging the latch lever 25 and rocking it so that it releases the frame 30 which is suddenly lowered by the weight 32 ; as a consequence the completed roll tends to move forward with the centre thereof passing beyond the plane joining the axes of the rollers 10, 12 and the continuous rotation of the three rollers ejects the roll towards the front of the machine. The roll as it is ejected engages the cross-bar 37 on a lever 38 and sets in motion the automatic mechanism for starting the winding of a fresh roll, while the roller 10 returns to its normal position and is relatched therein by the lever 25. The rod 23 may be actuated by hand or through a counting mechanism controlling the length of sliver wound on the roll while the descent of the frame 30 may be used to initiate the operation of the starting arbor or fork 82. Specifications 369,336 and 485,278 also are referred to. According to the Provisional Specification ejection of the sliver roll may be caused by displacement of the rear lower roller or of the upper roller.
