摘要： 788,405. Feeding webs. BRITISH UNITED SHOE MACHINERY CO., Ltd. (Boston Machine Works Co.). May 11, 1956 [May 12, 1955], No. 13699/55. Class 100(1) A machine adapted for feeding adhesive strip material and for severing from it a length suitable for application to a workpiece (e.g. a shoe upper) comprises a feed wheel which engages the web, cutter means for varying the length of material to be cut, and gauging means arranged to align with opposite ends of a workpiece thereby to measure its length. As shown a tape T is carried by a roll on a bracket 54 (Fig. 1) and passes over a guide 56 to the periphery of the feed wheel 46 in such a way that the adhesive face of the tape engages the wheel. The wheel 46 is mounted on a shaft 26 journalled in side frame members 22 of the machine which also carries a shaft 24 driven through the medium of a one-revolution clutch 28 (Fig. 5) and gear train 30 from a motor 34. The shaft 24 carries a cutter 42 adapted to cut the tape as at 52 (Fig. 2). The shaft 24 carries an eccentric 94 around which is an eccentric strap 92. A ratchet wheel 80 is mounted on the shaft 26 which is actuated by a pawl 90 connected to the eccentric strap 92 through a bell crank 96, and arms 98 and 100. For the purpose of varying the distance through which the feed wheel is rotated a cam member 110 is provided on a collar 76 on the shaft 26. The cam is adjustable by means of a link 86 and is connected to a link 74 which operates a movable gauge member 66. The length indicated by the gauge member corresponds to the peripheral distance moved by the feed wheel. To reduce noise and wear on the ratchet wheel a disc 116 (Fig. 7) with a large central aperture is loosely mounted on the shaft 26. The disc is provided with recesses 118 and 124 for engagement by a pin 112 on the pawl 90, the recess 118 being low enough to allow the pawl to engage the teeth in the ratchet wheel. As the pawl begins its operative stroke the pin 112 is located in the recess 118 and the disc is turned with the ratchet wheel until a pin 136 on th disc engages a stop 132 at the end of the pawl stroke so that rotation of the disc 116 is stopped and the pawl pin rides into the recess 124 whereby when the pawl is retracted the disc is rotated back to its initial position until the pin 136 engages a second stop 134 to stop rotation of the disc 116, the pawl pin then riding into the recess' 118 and on to the cam 110. To prevent overrunning of the feed wheel a brake drum 142 is fixed on the shaft 26 adapted to be engaged by a brake shoe 144 on an arm 146 spring- biased into braking position. The arm carries a cam follower 156 which co-operates with a cam 152 fast on the shaft 24 so that as soon as the shaft 24 has completed its single revolution the cam follower 156 drops into.the recess 154 of the cam 152 to allow the brake shoe 144 to engage the drum 142.

摘要： 299,528. British United Shoe Machinery Co., Ltd., (Boston Machine Works Co.). Aug. 2, 1927. Affixing tape.-A machine for applying adhesive tape to sheet material, of the kind described in Specification 220,502, is provided with means for severing the tape which are operated by the tapeapplying means under the control of the operator, and with means for feeding the cut end of the tape to applying position which are actuated from the tape applying means and brought into operation by the severing means. The tape is applied by means of a head 7 co-operating with a work support 1, the head being actuated from a cam shaft 14. The tape 3, fed round a shaped member 5, is severed by a pair of cutters 16, 18 the latter of which is slotted and fixed, while the former is reciprocated vertically by a strut 28. The latter, normally in the position shown, can be moved to the right by means of a catch 35 pivoted to a lever 32 operated by depressing a part 34 manually. Movement of the strut 28 to the right brings a depression 29 into engagement with a member 26 carried by the constantlyreciprocated head 10, thus causing the knife 16 to descend and sever the tape; this downward movement also frees the end of the strut 28 from the catch 35 and the former is restored to inoperative position by a spring 30. Movement of the strut 28 also actuates a pivoted member 42 which is provided with a tape-feeding finger 40 and is pivotally connected to a link 53 having nose 63 normally lying in the path of a pin 62 on a pawl 59, and rendering it inoperative. The pawl is carried on the reciprocating head and is adapted to ensage a ratchet 56 when the link 53 is moved out of the path of the pin 62. The ratchet is furnished with a crank pin 55 riding in a slot in the link 53, so that the movement of the member 42 by the strut 28 moves the link 53 out of the path of the pin 62 and renders the pawl 59 operative; the ratchet 56 is thus rotated and the member 42 operated to feed the tape. The movement of the member 42 ceases when the link 53 again resumes the position shown, and prevents rotation of the ratchet 56 by engaging the pawl 59.
