1964Peters Machinery Company develops a two lane stencil system utilizing holes in a rotating tube rather than a belt.

Cream Preparation traditionalCream Preparation - TraditionalCream Preparation traditional• Traditionally the cream is prepared in upright mixers using plasticized fat and powdered sugar. Discharged into dough troughs which are manually moved to the sandwiching machine and shoveled into the cream hopper.

Cream Preparation ContinuousCream Preparation - ContinuousCream Preparation Continuous• Ingredients are fed into a premixer then sent to the buffer tank.  It is then pumped through a scraped surface heat exchanger before being pumped to the stencil heads.
