Slitter Rewinds

Proud Builders Of The "Non-Standard" Slitting Machine

We are known in the converting industry for our custom machinery. Even through we have built hundreds of slitter/rewinders over the years, we don't boast about our line of standard slitters because, to us, nothing is truly standard.

Fortunately, our Clients seem to like that about us!

Most of our slitter/rewinder Clients need a special machine for special applications and materials. Often, their materials are also new to them. They come to IMC because their unique requirements are usually not satisfied by standard off-the shelf equipment.

Our goal is to match our expertise in slitting, winding and tension control with our Client's expectations for the right machine. To achieve this, our engineering team works directly with each Client to understand their requirements before the design phase is complete.

While we pride ourselves on our custom machine design, we have been building slitters for over 40 years and have many existing designs that may closely match your needs. Please feel free to send us you requirements so we can evaluate your project.

We invite you to browse through the following photographs and brief descriptions which illustrate our capabilities.

62" Slitter/Rewinder for Maximum Operating Flexibility

Designed for coated films, this slitter offers maximum operating flexibility with full-width web inspection, bi-directional operation and precise programmable tension

The driven, shaftless unwind has center-justifying capability for 28"-62" supply rolls

An easily removable slitting cartridge simplifies frequent slit width changes

A motorized roll elevator assists supply roll loading and a gin pole off-loading assembly removes finished rolls at the cantilevered-supported duplex rewind

Individual, adjustable width pneumatic lay-on rolls provide rewind packing roll pressure

The rewind mandrels unlock from their supports for convenient unloading

Slitter/Rewinder with Inspection Capability & Zero Product Backbend

For unidirectional prepreg tape, the slitter is specifically designed for adhesive coated single or multi-ply advanced composites with/without a liner

The unique design processed the material without any "backbend" that may cause delamination

The machine has a lighted inspection/splice area, bi-directional operation, and laminating capability

Versatile 62" Slitter/Rewinder for Tension Sensitive Applications

Center, Differential, Center/Surface, or Minimum Gap Rewinding make this slitter extremely versatile for different materials

Talk to us about our Slitting and Traverse Winding Systems

Traverse wound spools are an effective way to eliminate production and machine downtime caused by constant changeovers and splicing of conventional pads/pancakes.

Depending on material thickness and width, 10-20 miles of a continuous strand of material can be spooled on 1 core. That means downstream processes could run non-stop for an entire shift and in some cases, 2 shifts!!!
