Definitions

  • the immediately preceding sheet material assemblage 74a (FIG. 2) is registered with its back or folded edge portion 96 extending parallel to the blades of the face knife 22 and perpendicular to the blades of the head, foot and split knives 44, 46 and 48 by retractable stop members 100 at the first trim station 38.
  • the sheet material assemblage 74a is being front registered against the stop members 100, it is side registered by engagement of its foot portion 82a against a second side register surface 104.
  • Spring fingers 106 similar to the spring fingers 88, press the head edge portion 92a of the sheet material assemblage 74a toward the side register surface 104.
  • the support assembly 200 includes a movable or upper support block 202 which is reciprocated with the block 204. This reciprocating movement of the upper support block 202-is guided by guide posts 206 (only one of which is shown in FIG. 1).
  • the movable knife blade54 of the head knife 44 is mounted on the movable support block 106 while the set of conveyor belts 32 and stationary knife blade 62 are mounted on the base support bloc-k 204.
  • the sets of conveyor belts 32 and 34 and knives 44 and 46 move inwardly and outwardly together with the support assemblies 172 and 200 on which they are mounted,
  • the sets of conveyor belts 32 and 34 are indexed or moved through a feed stroke to advance the sheet material asbelts can be moved through only feed strokes without intervening return strokes.
  • the drive member 290 re- 'mainsst ationary and'the sheet material assemblages are held stationary in the registered orientation relative to the knives of the trimmer mechanism 20 by the sets tuator pin 284 engages the acceleration portions 312 of extend perpendicularly through the axis of rotation of the drive member 290. Therefore, each time an actuator pin 282, 284 or 286 is moved-along the cam tracks 306 from the position shown in FIG. 9 to a position just slightly past the position shown in FIG.
  • the drive pulleys for the two sets of conveyor belts are moved axially along the shafts 326 and 338.
  • the pulleys are mounted on undercut sleeves 390 (see FIG. 14).
  • the sleeves 390 are undercut, as indicated at 394 in FIG 14, axially outwardly of the extensions 192 from the'base support blocks. Therefore,
  • the simultaneous adjustment in the positions of both trimming knives 44 and 46 and the associated sets of con veyor belts is believed to be particularly advantageous in that the flow of sheet material assemblages is maintained along the center line of the trimmer mechanism 20.
  • the accommodating of sheet material assemblages of different sizes is further facilitated by the mounting of each of the two side register devices 104 and 106 for movement with an associated one of the sets of .conveyor belts 32 and 34 and trim knives 44 and 46.
  • An apparatus for trimming sheet material assemblages along face, head and foot edge portions comprising first knife means for trimming the trim station, fourth knife means disposed at the second trim station, intermediate said first and second knife means for cutting each of the sheet material-assembeing reregistered. Since there are two sets of conveyor I belts 32and 34 which continuously grip the sheet matethe trimming knives 44 and 46 and'the two sets of conveyor belts 32 and 34.
  • the head knife 44 and associated set of conveyor belts 32 are moved as one unit while the foot knife 46 and associated set of conveyor blages in turn between the head and foot portions of the sheet material assemblages, registration means at one of the trim stations for positioning each of the sheet material assemblages in turn in predetermined orientation with said first, second and third knife means prior totrimming, andconveyor means for holding a sheet material assemblage in the predetermined orientation at said one of thetrim stations as it is trimmed by at least one of said knife means, for transportingthe sheet material assemblage from the one trim station to the other trim station, and for maintaining the sheet material assemblage in the predetermined orientation as the sheet material assemblage is transported to and trimmed at the other trim station, said conveyor means including first belt means extending between the trim stations for clampingly engaging a sheet material assemblage adjacent to its head portion at the one trim station and for maintaining this clamping engagement as the sheet material assemblage is transported to the other trim station and second belt means extending between the trim stations for clampingly engaging'a sheet material assemblage adjacent to
  • An apparatus as set forth in claim lfurther including adjusting means connected with one of said first one of said first and second'belt means and the other first belt means and said second knife means relative to said fourth knife means and for simultaneously moving said second belt means and said third knife means relative to said fourth knife means.
