Machine Model for Improvement

Pemco packaging machine Model 34 and 37

Description of Improvement

This upgrade is part of the Technical Improvement Program (TIP); it installs a ream squaring mechanism by the elevator. The squaring plates allow the ream to be precisely centered on the elevator prior into folding section. 

This consistent centering also centers the ream between the tuckers, preventing jams or unnecessary widening of the machine. This design is similar to ream squaring mechanism found in the high-speed ream wrappers. The ream squaring mechanism is driven with a new mechanical linkage from the loader lever arm.

A hand wheel is included for size change and fine tuning for a given product. The existing loader lever is replaced with a new lever that has provision for connecting a rod and an arm that drives the pivot shaft. This upgrade also eliminates the infeed guides. As a result the bottom plates for the vertical infeed drive belts are replaced along with two new guide rails by the stop gate. Additionally, filler plate guards are used to protect the open area created by removing the longer infeed guides.


  • Reduces product damage and improves ream quality
  • Eliminates infeed guides - no contact with product
  • Precisely centers the ream on the elevator by forming a 鈥渂ox鈥 between the loader fingers, back stop, and squaring  plates

A sheeter that we had planned especially for our lightweight specialty papers has become an all-round smart sheeter that can process even heavy grammages up to 300 gsm with maximum cutting accuracy.
