Title: Improvements connected with envelope making machines
IPC: B65H9/06
Filed: 1922-10-17
Abstract: 204,547. Wycherley, S. R., and Smith, W. R. C. Oct. 17, 1922. Envelopes, making.-In envelope-making machines of the kind described in Specification 3231/11, reciprocating means are provided for properly positioning the blank before it passes to the first set of gummers and folders and also for properly positioning the partly-made envelope before it passes to the second set of gummers and folders. The blank 17, Fig. 1, is positioned by four fingers 19 attached to a rod 10 which is supported by the lower arms of a pair of bell-crank levers 8, Fig. 2, pivoted in the frame of the machine. The other arms of the levers are connected by a rod 9 carrying a roller 11 which rides on a wheel 12 provided with two cams 13. On the same shaft as the wheel 12 is mounted a wheel 15 having two oppositely-disposed rubber studs 16 for engaging the blanks. The timing is such that just as a blank is fully drawn off the pile, one cam 13 is leaving the roller 11 and the spring is pulling down the upper arms of the levers to bring the fingers 19 into contact with the feed board 22. When a half revolution is nearly completed, the studs 16 act on the top blank and feed it against the fingers which rise almost immediately by the action of the other cam and allow the blank to be drawn off the pile and passed between the guide rods 5 and chains 6 to the gumming &c. devices. As soon as the edge of the partly-made envelope reaches the stop 23, Fig. 6, the envelope is gripped by a clamp 24 which is lifted immediately to permit the stops 37, Fig. 5, on the chains 38 to engage the envelope and carry it to the finishing appliances. The clamp 24 is carried by a rod 25 connected by a cross-piece 26 to a rod 27 which is reciprocated by the action of a cam 31 on a roller 30. The clamp 24 may be shaped to conform to the edge of the envelope.
