JJF Slitter Rewinder

JJF Slitter rewinder for slitting and rewinding of narrow width, small diameter rolls with shaftless rewind mandrels for automatic slitting and processing.


The model JJF slitter rewinder is ideal for fully-automatic production of narrow width, small diameter (up to 10″) rolls. No other company in the world has installed more fully automated POS roll slitter rewinders in North America than Jennerjahn Machine, Inc.

No rewind mandrels are required with the JJF. Cores are simply poured into a hopper/bowl feeder system and automatically processed. The simple and innovative shaft-less rewind system eliminates the need for rewind mandrels.

Upon seeing a demonstration, converters recognize the value of the machine’s simplicity and immediately understand how it will reduce labour, provide more consistent and reliable production, improve finished roll quality, and make them more efficient.
