Machines llw6 and llw8 are fitted with hand driving attachment, have a rotary hook and make the lock stitch and are intended for use in cotton mills for joining the ends of tape or canvas belts which drive the cotton winders and twisters on the spinning frames. The joining of the ends of the belt is done by lapping one end of the belt over the other and sowing the two ends together with several short parallel lines of stitching which are made lengthwise of the belt and uniformly spaced apart across the width of the belt, as shown in Fig. 11, page 14. The machines are fitted with a special belt guide attachment which is adjustable to accommodatc belts up to 2i" w ide. Ί lie belt guide is connected with a pivoted lever bv which tile belt can be moved sideways to make the distance between the lines of stitching either j'., or r,, inch, as desired. Jii addition, the machines have a reversible drop feed, controlled bv a conveniently located hand lexer which enables the operator to feed the material backward or forward and thus make the successive parallel rows of stitches without turning the belt being sewn. Machine llw8 is mounted on wood base. Knee lifter 221899 is provided for raising or lowering the presser foot.
