Abstract
Apparatus for cutting an extrudate to finished length includes a hopper that receives rough-cut lengths of extrudate, and feeds them one at a time to holders on a movable carrier. Each holder captures a length of extrudate which is transported by movement of the carrier to a pair of heated blades spaced apart a distance equal to the desired finished length of the extrudate. The blades serve to cut a portion from each end of the extrudate in a holder, whereby the extrudate is trimmed to finished length, and, simultaneously to fuse the material of the extrudate at the end faces, thereby sealing such faces. Further movement of the carrier enables the holders to release the trimmed extrudate onto a conveyor.
Claims15
Apparatus for trimming an extrudate to finished length and fusing the ends thereof, comprising:
- a. hopper means for receiving and orienting rough-cut lengths of extrudate, and having an outlet through which oriented lengths of extrudate are adapted to pass;
- b. a movable carrier having a plurality of spaced holder means operatively passing the outlet as the carrier moves;
- c. each holder means adapted to releasably capture a length of extrudate from the outlet as the carrier moves the holder means past the outlet;
- d. a pair of spaced, rotatable cutter discs operatively positioned relative to the carrier for trimming each end of a length of extrudate captured by a holder means as the carrier moves the holder means past the cutter, discs and
- e. means for heating the cutter discs whereby each end of the length of extrudate is fused simultaneously with being trimmed.
