IPC: B31B19/00
Filed: 1960-04-29
Abstract: 934,941. Making envelopes. DAVID CARLAW (ENGINEERS) Ltd. April 24, 1961 [April 29, 1960], No. 15056/60. Class 94(2). An envelope making machine of the rotary type for folding and sealing down the bottom flaps of envelopes and folding down the sealing flaps is characterized in that the section of the machine arranged to fold down the gummed sealing flap comprises a suction roller 83, a co-operating roller 82 which engages the back of the envelope, the peripheral surface of the co-operating roller being formed to avoid contact with the gummed tip of the envelope, and a folding roller 93 which engages the front of the envelope, the suction being so timed that the sealing flap 30, during its passage between the suction and folding rollers is first nipped and then held against an undercut surface 92 of the suction roller 83, so that the gummed tip does not contact the folding roller or the envelope body. Envelopes, having folded-in side flaps 42, are fed in between rollers 60, 61 where adhesive is applied to the side flaps 42 by the roller 60; the adhesive being supplied from a bath 64 via rollers 65 to the roller 60. The envelope is then conveyed by means of a suction roller 62 to the first folding section, where the bottom flap 24 is pressed into adhesion with the side flaps 42 between rollers 70, 63 the suction port 63A engaging the front of the envelope and conveying it through the nip. The envelope is then conveyed past a guide 71, and between pairs of rollers 73 to the second gumming section where adhesive is applied to the sealing flap by the roller 80. It is then conveyed by the co-operating roller 82 of arcuate section to the final folding section, where the trailing sealing flap is seized by suction ports 90 along the crease 46, and as the envelope is urged through the nip between rollers 83, 93, suction ports 91 on the undercut surface 92 of roller 83 hold the gummed edge 30A of the sealing flap away from the body of the envelope. The envelope is impelled by ribs 53 to a drying conveyer beneath, (not shown). In an alternative arrangement where it is desired to apply adhesive to the side flaps and sealing flap using a single roller to prevent the upper co-operating rollers contacting the gummed edge of the sealing flap during conveyance through the machine, these rollers are in one case, cut away to form a sector, and in another case formed with a groove in the periphery. In both arrangements, the speeds of the different rollers are arranged with respect to position and relative size to produce a constant conveyance speed through the machine.

Control circuit, Fig. 3. A signal on lead 32 representing power consumed by rotor drive motor 13 passes via buffer amplifier 34, and, when the mixer, Fig. 1, is unloaded the power signal passes via short time constant integrator 37 to digital voltmeter 39, in the no-load mode set by switch 36, registering motor power, whence potentiometer 51a is set for zero reading of voltmeter 39, to ensure that, when the power consumed by the motor 13 in working the elastomer in the loaded mixer is integrated by integrator 47 whose output is fed to the voltmeter 39 now registering energy consumed, the no-load power does not contribute to the integrated signal. The reading of meter 39 may be displayed, see Fig. 2 (not shown), so that an operator can control the addition of further ingredients to the mixture, or its unloading, when predetermined readings are indicated, or a pre-set energy value may be set on thumbwheels (54) (Fig. 2) and when such energy has been consumed, relay 42, 43 is operated to re-set the integrator 47, and motor 16 is energized to unload the mixer. Switch 49 enables selection of a suitable range for energy consumption. Mixer, Fig. 1. Material is added via orifice 17, there being a movable wall 18, and pressure ram 19, withdrawn for loading.
