Abstract: 1,106,682. Making manifolding sets. P. M. BELL. 18 June, 1965 [18 March, 1964], No. 11537/64. Heading B6A. Manifolding sets comprising sheets of carbon paper- and record sheets, or record' sheets with carbon coatings on the rear, and particularly comprising sheets of assorted sizes, Fig. 2 (not shown), are gummed together into pad form B by spots E of adhesive along the top edges in an apparatus which includes adhesive-applying pads 57 controlled by solenoids SW which are connected to a source of power through a stopping-switch. After gumming, the pads are fed between pressure rollers 21, and. subsequently through perforating rollers where they are perforated along a line F. The bottomsheet of the pad B is as wide as the widest sheet, and is placed on a reciprocable table 10 with its top edge beneath pins 13a and against a bar 13. The right edge of the sheet is located by fingers 46 on arockable rod 44, and the left edge by magnetic bars 20, Fig. 1 (not shown). The appropriate number of pads 57 are oscillated to pick up adhesive from a roller 52 rotating in a bath 51, and to apply adhesive spots E across the sheet, when a foot switch is closed. Further sheets are placed in turn over the bottom sheet, and each receives spots of adhesive appropriate to the width of the next sheet above. When the top sheet is placed in position, the pads 57 are not operated when the foot switch is closed, but a motor 15, Figs. 4 and 9 (not shown), is energized to cause the table 10 to move towards the rollers 21, rocking the fingers 46 and feeding the pad B between the rollers. The gluing, mechanism 11, Figs. 4 and 7 (not shown), comprises a cross-bar 56 carrying a number of pads 57 mounted on the armatures of solenoids SO 1 , SO 2  &c. spring-urged upwardly into inoperative positions, and each solenoid has a three-position switch SW 1 , SW 2  &c. The bar 56 is pivotally mounted by links 58 to a cross-shaft 59 which is oscillated by a motor 61 through means 62-66, whereby the bar 56 is oscillated to bring the operative pads 57 first into contact with the glue roller 52, and then into contact with the sheets on the table 10. The glue roller 52 is automatically ratchetoperated, and can be rotated also, during the working-up period, by a solenoid 75. The switches SW 1  &c are pre-set so that the minimum number of pads 57 to be used are permanently operative, and so: that the remaining pads to be used can be controlled by the stepping switch. The stepping switch RCS, Figs. 8 and 9 (not shown), comprises a fixed ring 98 in which is rotatably mounted a contact plate 99 secured on a shaft 100 carrying three slip rings SR 1 , SR 2 , SR 3 , connected through brushes to the terminals T 1 , T 2  and T 3 , respectively. A ring 101 secured to the plate 99 has contact studs 102 thereon, all but two of these studs being connected to the slip ring SR 1 : of these two, one. is annealed to the slip ring SR 3 , and the other is a blank stud. A sweep arm 103, arranged to move over the studs 102, is secured to a shaft 104 concentric with the shaft 100, and is rotated by a solenoid SOL 1 through a ratchet 105 and pawl. A second solenoid SOL 2 controls a holding pawl for the ratchet 105, so that the sweep arm 103 can be returned to initial position by a coil spring 107 The shaft 100 carries a knob 109 whereby the plate- 99 can be pre-set relatively to the zero position of the sweep arm 103. A pawl 111 acts as a click-stop for the plate 99. In operation, the knob 109 is rotated toset the switchforthe desired numberof sheets C of the manifolding set B, the machine is operated by the foot switch 88 to cause the operative pads 57 to apply adhesive to the bottom sheet of the set B, and the solenoid SOL 1 moves the sweep arm 103 one step. This is repeated until the top sheet is placed in position, but the arm 103 now engages the blank stud 102 and the pads 57 are rendered inoperative. When the switch 88 is again operated, the arm 103 contacts the stud 102 leading to the terminal T3 to start a motor 15 which drives the table 10, and the set B of sheets is fed between the pressure rollers 21 and; the perforator rollers. The solenoid SOL 2 now returns the sweep arm 103 to zero position for a new operation.
