And what are the end-products?

the slitter teamLet’s face it; if you’re not familiar with the converting industry, chances are you don’t know what a slitter is. Often times when I tell someone that I work for Jennerjahn Machine and tell them that we manufacture high speed fully automatic slitter / rewinders for the paper converting industry, their next question is, “What is a slitter?”

slitter end productsSo, I usually begin by listing a few examples of end-user products that they are familiar with such as cash register rolls, credit card and ATM receipts.

Next, I’ll explain how those small rolls of paper in cash registers and ATM machines start out on one big 54 inch wide master roll and are slit down and wound up into several smaller rolls. A slitter / rewinder machine is what is used to make these rolls and that is what we build at Jennerjahn Machine.

There are also different types of slitter / rewinders depending on the material being converted. These include; surface wind slitter, center wind slitter, and duplex wind slitter.

Jennerjahn Machine Slitters

slitter roller diagramJennerjahn Machine’s surface wind slitters feature a front and rear bedroller, nip roller and a top rider roller. Cores are cradled between the front and rear bedrollers and surface wound to the desired roll length or diameter. The nip roller is used momentarily to hold the web in place during roll changeovers. The top rider roller rests on the top side of the cores during the winding cycle. Depending on how much down pressure and/or torque that is applied to the roll determines on how hard or soft the roll will be wound.
