Bearing brackets 49 and l5I are bolted to opposite ends of a rocker arm 52 which is keyed on a shaft 53 journaled on a bearing frame 54. A lever 56 is keyed lat its inner end Ito the shaft 53 and is pivotally connected ait its outer end at 51 to a piston 58. The inner endof the piston 58 'is mounted f'orreciprocable movement within a cylinder 59 which is pivot-ally mounted at 6| .to a bracket 62. A c-ounterweight arm 63 is keyed at its inner end .to the shaft 53 .and extends outwardly Ain substantially parallel alignment to the rocker arm 52 to receive acou'nterweightv l64, the 'counterweight being adjustably secured tothe free end ofthe arm 63 by means of a set screw 66.

o'nduits 61 and 68 lead from-fthe frontand rear ends, respectively, of the cylinder 59 to a four-way valve 69 which is connected to a source of iiui'd under pressure by means of a conduit 1 I. A return conduit 12 leads from the valve 69 lback to a reservoir, not shown; The valve 69 is provided with an operating handle 13 having its free endfengaged by a plunger 14 of asolenoid 16. 'I he -ree'end of the handle 13 is also engaged by one end of'a tension spring 11 which has its other end secured to av frame 18. The valve `69 is normally heldin the position illustrated in Fig. 1 to direct huid under pressure through the conduit 61 and into the forward end rof the cylinder 59. W'hen the solenoid 16 is energized, the valve 69 is actuated to direct iluid under pressure through the conduit 68 into the'rear end of the cylinder 59 to move the piston 58 towardlthe frontend of the cylinder. i Y

lA'deflector roll 8| is journaled at its ends in the frame 6 and :is provided withv a corrugated surface for engagement with thefrontedge of the advancing sheet 1. As illustrate-d in Fig. 1, the deector roll is rotated ina clockwise direction to direct the ysheet material upwardly between the upper conveyor- II and intermediate conveyor 28. The deflector roll 8| is rotated in a counterclockwise direction to direct the sheet material :between the intermediate :conveyor 28 and the lolwer conveyor I2. Theameans employed'for driving ,and control ling the operation ofthe winding apparatus is diagrammatically.'illustrated in Fig. 2 in the drawings. The flying shear members and 9 `are driven-in timed relation byl means of a pair

ofy meshing gears

82 and 83,v the shear member '.8 being vdriven by means of a suitable electric motor 84, acting through a suitable transmission 86; A pair of gears .81 and 88 are' secured to the conveyor'driving shafts I4 and 22, respectively, and are driven by means of an electric motor 89 actingthrough suitable gear transmission 9|. A gear 92 is `secured/to the .intermediate -conveyor driving'shaft 323 and is vdriven-by a reversiblel velectric motor 93 `acting'through suitable transmission 94. A brake drum 96 is interposed in the power transmission shaft between the motor 93"and the/driving shaft 33 to be engagedby a friction lever 91 which is -movedintorfrictional engagement with Vthe brake drum 96by means ofv a compression spring 98. The brakeqarm 91 is drawn :out of frictional engagement withthe brake drum 96 by means of a plunger 99 actuated by -a solenoid The mandrel-29 is [driven by a motor |02 acting through a suitable transmission ID3; and the mandrel 3| lisdriven by a motor |04 through a suitable transmission |06. The motor 84 is connected to a source. of` current by means ofleads |01 and |08, Aandaswitch i lead |212.

mandrel 3 I.

09 is interposed in lea-d |08 to control the operation of the motor. The motor |02 is connected to a source of current through lead I|I, switch I|2 and lead H3; while the motor |04 is connected to a source of current through lead Ill-I, switch I I2 and conduit ||4. The reversing motor 93 is connected to a source of current through the lead IIB, 'rotary switch |I1 and lead H8. The solenoid 16 is connected to a source of current through lead II9, rotary switch |2I, and The solenoid |0I is connected to a source of current through lead II 6, rotary switch 'I`I1 and lead |23.

`-In the operation of the Winder apparatus, the sheet'material 1 is adapted to be moved continuously-through the feed rolls `4-|| and then between the forward ends of the upper and lower conveyors II and |=2. When all the con@ veyors are in the positions illustrated in full lines in Fig. 1, the forward edge of the advancing sheet 1 is engaged by the deector roll 8| which is turning in a'clockwise direction to direct the sheet material upwardly between the upper conveyor II and intermediate conveyorV 28,. The forward edge of the advancing sheet is engaged in one of the'recesses provided in the collapsible mandrel 29 which is rotated in a counterclockwise direction by the motor I 02 until a roll of sufficient diameter is formed thereon. ,1

lWhen the roll of sheet material on the mandrel 29 reaches a predetermined diameter, the switch |09 is closed to cause the flying shear to rotate one complete revolution to cut the sheet 1 trans- Versely. During rotation of the ilying shear, the rotary switch I|1 Vacts to break and then complete thev -circuit to reverse the directionof rotation of the motor 93 and thus acts to reverse "the direction of rotation of the drivin-g pulley 36 `of the intermediate conveyor 28. The deector roll 8| is then caused to rotate in a counterclockwise direction by means of a train of gears comprising a driving gear: |26, an intermediate gear |21 and a driven gear `|28. During alternate `revolutions of the ying shear, the solenoid `16 l is energized 'to actuate lthe four-way valve 69 and Vcause vthe piston 58 `to -move outwardly to pivot the rocker arm 52 which, in turn, acts through connecting rods 43 vand 41 to raise the conveyors l|| and l2 and lower the conveyor. 28 to the position indicated indotted outline. The

switch ||,2'is moved to its dotted'position to complete the circuit to the motor |04 to rotate the It will thus be seen that the forward edge of the advancing sheet 1 will first be engaged and directed by the deilector roll 8| into position between a pair of endless conveyors which in turn act to direct the advancing sheet toward a mandrel for winding. The mandrels 29^and 3| are preferably of the collapsible type to facilitate removal of a roll oi sheet material from one mandrel while the sheet material is being wound on the other mandrel. During operation of the'i'lying sheanit will be noted th'at the rotary switch II1 breaks the circuit to the solenoid 16vand permits the friction arm 91 vto be moved into frictional engagement with the. brake drum, 96 by means of ythe compression spring 98 to stop rotation ofthe -motor 93 and the parts driven thereby prior to reversal of rotation of the motor. During the operation of the apparatus, theupper and lower conveyors Y| and I2 are driven continuouslyY in the directions indicated by the arrows by means ofthe motor 89. 1 It is. contemplated 5. that the switches: H19: and VH2 maybesoperated manually ar-automatically. l-
