MODEL 80

FIBER GLASS ROVING CARTRIDGE CUTTER

  • Drawer-Type Cartridge. A completely serviced cutting assembly (cartride) slips in and out like a drawer for sevice or fast exchange. Production may be resumed immediately. Ideal where lost time is expensive while servicing choppers, as on mat and preform machines, but excellent for any cutting application.
  • Heavy-Duty, Rigid Construction. Chopper is made for long, trouble-free life with oversized, sealed ball bearing throughout.
  • Large Cuting Capacity. Guard permits roving introduced uniformly at 1/4" centers over 4" working face, if desired. Can cut up to 6 pounds per minute.
  • Simple Servicing. All cutting elements simply snap in or out of place for renewal. When reassembled by snapping back, the original adjustment is retained.
  • Economical. Blades are inexpensive edges similar to razor blades except 4" long. May be set up to use conventional razor blades if specified (a FINN & FRAM innovation for fiber glass cutters in 1955).
  • Convenient. Roving may be inserted safely while the cutter is operating. Roving guide is also a complete wraparound guard. Guard pivots out of the way for servicing the cutting elements.

Standard features exclusive to Finn & Fram

POSITIVE DRIVE ANVIL SLEEVE- No slippage on core. No dirt from inside wear. Special compound for exceptional performance.
SELF-ADJUSTMENT AND WEAR COMPENSATION- Steady spring pressure gives uniform cutting pressure. Constant readjustment is eliminated on Model 80 cutter. Normal servicing never affects permanent adjustment nor does anvil roll wear. Built-in scale reads applied pressure.
PARTS LIST & INSTRUCTIONS CAN'T GET LOST- Complete operating instruction and expendable parts list are printed on metal plate mounted on face of cartridge - always available at point of use.
GUARDING- Drive is enclosed. Cutter rolls are under feed grille so guarding is automatic. Feed grille permits many feed positions and locates roving accurately. Roving may be started easily from many positions while cutter is running.
Many modifications not listed are available to meet special applications.
