Abstract: A gussetting machine having adjustable spans between the gussetting fingers. The gussetting fingers on opposite sides of a wrapper move in opposite directions driven by rotating a spline shaft which engages a hub having an angled bore therethrough such that the surface of the hub nutates with a pitch and yaw motion. A housing riding on the surface of the hub experiences the pitch and yaw motions. A bracket surrounding the hub has a shaft for allowing the hub to rotate about the pitch axis. A the bracket is pivotably mounted on a pivot block to allow the bracket to yaw. Gussetting arms attached to the brackets swing back and forth in opposite directions simultaneously. The angled bores in the hubs are 180 degrees offset from each other such that the gussetting arms move in unison in opposite directions. The angles of the bores can be increased for larger gussetting arm swings or decreased for smaller gussetting arm swings.

Abstract: A cutting head apparatus for use in a high speed horizontal wrapper. The apparatus has two modular cutting heads each with a cutting shaft. The cutting shafts cooperate for cutting and sealing wrapping material between the products being wrapped. The cutting shafts are journaled for rotation in bearing blocks located on opposing ends of the shafts. Each modular cutting head can be mounted in at least two operative positions on a cutting head support frame. The bearing blocks of the modular cutting heads are mounted on the cutting head apparatus to permit movement of the shafts away from the cutting area in the event a product becomes misaligned and the cutting blade and anvil contact the misaligned product.
