Abstract: 1,100,032. Apparatus for making trimmings; winding webs. CHEADLE ROYAL (INDUSTRIES) Ltd. 12 May, 1966 [13 May, 1965], No. 20179/65. Headings B6B and B6G. [Also in Division D1] Paper festoons are manufactured by apparatus comprising a sewing machine 10 for sewing a line or lines of stitching down the centre portion of a strip of paper, a pleating means for producing pleats to be immediately fixed by the said stitching and one or more winding mandrels 18 adapted to be driven so as to rotate synchronously with the stitching operation and arranged so that it or one of them will receive the stitched pleated strip, to wind it into a roll, there being a weighted member 21 which in use rests on the middle portion of the strip being wound to keep the edges of the strip substantially parallel. As shown the pleating means comprises a pusher blade 12 which is reciprocated by means of a crank and crank rod 11 the crank being driven by the sewing machine; from the sewing machine the strip 13 passes through a U-shaped trough 16 in which a roller 17 rests on the strip; the strip then passes to one of two said mandrels 18, the mandrels being slotted. The mandrels are driven from the sewing machine through a friction clutch. When the required amount of strip 13 has been wound on to the mandrel 18 the roll is removed endwise from the mandrel. Each mandrel is provided with a manually operable brake 21. The rolls of pleated strip which are removed from the mandrel 18 are put into a carrier or magazine (not shown) of apparatus, Fig. 2, which enables strips of different colours to be connected together and the composite strip cut to a required length. The carrier or magazine contains several rolls of the pleated strip 13 of different colours; the carrier or magazine moves about a vertical pivot and has a number of horizontal arms 13 each of which carries one of the rolls and on the vertical spindle carrying the arms is flat sided member having as many flat sides as there are arms to hold the rolls of paper, a spring bearing on one of the flat sides so that a particular arm can be selected; when the arm has been selected the end of the strip is fed between the nip of co-operating wheels 26, 27 the wheel 26 being driven and the wheel 27 being a follower wheel; the strip is then led to a take-up mandrel 28 the spindle of which is positioned in vertical slots 29 so that the mandrel is movable vertically; an endless belt or chain drive 30 connects the follower wheel 27 with a roller 31 which in turn drives two further rollers 32 and 33, the rollers 32, 33 supporting the take-up mandrel 28; hence as the drive wheel 26 is rotated by means not shown, the strip is pulled through the apparatus and wound on to the mandrel 28; as the diameter of the roll on the mandrel increases the spindle of the mandrel moves vertically and when a synchronous motor (not shown) actuates a solenoid 34, a lever 35 pivots an arm 36 on which the follower wheel 27 is mounted to lift this wheel clear of the driving wheel 26 whereby feeding of the strip through the apparatus stops, a solenoid 37 is then energized and causes a knife 38 to sever the strip 13. Another strip of different colour is then led from the magazine, its end joined to the end of the previous strip by means of adhesive tape from a magazine 25 and the process repeated.
