Abstract: 1308712 Inserting sticks in ice cream POLARMATIC CORP 7 April 1970 16302/70 Heading A2B [Also in Division B8] Apparatus for inserting sticks into blocks of ice cream comprises a hopper 12 to receive the sticks orientated parallel with themselves, a rotating wheel 14 extending within the hopper and having a plurality of spaced grooves 14b on the periphery to receive the sticks. The wheel 14 also has a peripheral groove 14c to receive a finger 15 movable between a position in said groove 14c to allow sticks to be picked up by the grooves 14b and a position extending into said grooves 14b to prevent such pick up of sticks. The wheel discharges the sticks onto a platform 19 and they are moved therealong in abutting relation and are subsequently delivered to an endless conveyer 23a. Arranged above the conveyer 23a at positions A and B are respective sensors 26a 27a controlling microswitches 26, 27 such that when the conveyer is full with sticks to the point A this is sensed and results in the finger 15 being moved into the position to prevent further sticks being picked up by the wheel 14 and when the absence of sticks at B is sensed the finger 15 is moved to its retracted position to allow further sticks to be supplied to the conveyer. The sticks on the conveyer 23a abut a stop 25a at the discharge end and are then moved transversely of the conveyer by a reciprocating pusher 32 actuated by a solenoid 31. The sticks S-2 then advance through contrarotating rollers 33 and in so doing push a preceding stick S-1 through a spring urged stop 34 and into an ice-cream block C. The block C is cut from an extruder 28 by a hotwire 29 rotating with a shaft 29a in timed relation with a receiving conveyer (not shown), which shaft also mounts a cam 29b to actuate a micro-switch 30 controlling the solenoid 31.

Abstract: 1330297 Feeding webs MOLINS MACHINE CO Ltd 9 Dec 1970 [10 Dec 1969] 60374/69 Heading B8R In a web feeding and splicing device associated with a wrapping machine provided with web draw off rollers (not shown) the expiring end 1a, Fig. 1, of the web 1 moving at a first linear speed is spliced with a leading end of a waiting web 2 by attaching the leading end to the expiring end and driving the leading end after the splice at a second higher linear speed by a pair of rollers 9, 18 the latter of which is movable relative to the roller 9. Higher linear speeds relieve tension in the splice until the splice has reached the rollers in the wrapping machine, the higher linear speed being possible due to a storage loop 2a formed by the waiting web 2. In operation a micro-switch arm 33 sensing the tension in the web 1 trips a micro-switch 34 when the expiring end 1a relieves the tension in the web, whereupon a solenoid 35, Fig. 1, energizes its armature 36 to actuate a onerevolution clutch 39 which causes a rotary arm 41 to trip a detent 30 such that a pivotally mounted blade 23 severs the suction held adhesive portion 21 of the leading end of the web and adheres it to the expiring end portion 1a moving over a splicing table 7 covered with a carpet portion 26. The clutch also causes a similar arm 40 to trip a detent 43 permitting a lever 38 to pivot a knife blade 56 and sever the remaining portion 1a which is held by a suction roller 5 whose periphery is co-operating with a brake 10 applied in consequence of pivoting the knife blade 56. Moreover, the clutch causes rotation of the rollers 9, 18 by driving the former through gears 54, 53, 55 and displacing the roller mounting block 19 by a drive 50. The rollers 9, 18 move the spliced web 2 at a higher rate than the rate of the web 1 drawn off by the machine draw off rollers, the web 2 being drawn off initially from a storage loop 2a and when the splice has passed the machine draw off rollers the tension in the web 2 is transmitted to the waiting web roll, when the rollers 9, 18 have been restored to their resting positions.
