Abstract: 692,053. Mops and apparatus for manufacturing them. BURSTENFABRIK WALTHER AKT.-GES. Dec. 18, 1950 [Dec. 27, 1949], No. 30784/50. Class 19. A mop comprises a flounce made of at least one rope of fibrous material, such as yarn, of indefinite length, which is inserted in axial bores provided in one of the flat faces of a short cylindrical stock so as to form loops between adjacent bores. The mop is made by forcing at least one such rope in succession into said bores, the rope portions between the bores being drawn out to form loops. The apparatus for carrying out the process consists of a trumpet for guiding the rope, a pusher engaging the rope in order to force it into the bores and a looper which is reciprocable in a linkage synchronously with the strokes of the pusher to seize the rope and form loops. Figs. 1 and 2 show a form of apparatus for making the mops and Fig. 3 shows a mop made thereby. In the Figures yarn ropes 1 wound on a rotary reel 2 are paid out by roller 8 into a trumpet 3, the roller being pivoted to the trumpet. In the trumpet the ropes are fed between two staple-guiding jaws 4 which are mounted on the end of a conically tapered' cap 21 in which is secured the trumpet 3. The trumpet comprises two walls 3<SP>1</SP> which are inclined relatively to form a funnel for leading the ropes between the jaws 4. The ropes inserted into the bores of a stock 17 are secured therein by a wire staple 5 which is formed of wire 6 which is supplied to a punch 10 and 10a, is pushed between the jaws 4 by the stroke of a pusher 7 and engages the ropes 1 led between the jaws. The rear end of the pusher 7 is pivoted to the upper end of arm 9 which may be actuated by an eccentric shaft. The pusher is reciprocated by the action of 9. A bell-crank 12, 13 is pivoted to 10a and its arm 12 is connected to the lever 9 through a link 14. The latter is pivoted at 15 to the lever 9 and rotatably mounted in one of the holes 16 in arm 12 and the bell-crank is oscillated through the action of lever 9. A rod 18 is fixed to the free end of the arm 13 and engages the ropes by its hooked end. The stock 17 is provided with a plurality of axial bores and is secured in a vice 20 which is moved in synchronism with the movement of arm 9 in order that at each stroke of the pusher 7 the bores in stock 17 are successively presented to the pusher. The ends of the ropes 1 are led from the reel 2, via the roller 8 into the trumpet 3, the pusher 7 being in the retracted position, and the hooked rod 18 being in the lower position as in Fig. 1. The pusher 7 is forwardly projected and pushes a staple 5 towards the front end of the apparatus. At the same time the arm 13 and the rod 18 are swung upwardly as shown in the broken lines in Fig. 1. The staple 5 engages the ropes which are pushed into a bore in 17 and secured therein by the staple. The lever 9 then swings clockwise whereby the pusher 7 is moved rearwardly and the rod 18 is swung into the lower position. During this movement the hooked rod 18 engages the loops to form a loop 19, a certain length of the ropes being unwound from reel 2. The pusher 7 is projected forwardly again, and at the same time the rod 18 is swung upwardly and a further bore in 17 is presented to the pusher. The ropes are again engaged by a staple and fixed into the bore. The process is continued until ropes have been fixed in all the bores. The arm 12 has a plurality of spaced holes 16 to allow the length of the loops to be varied.
