Slitting & Rewinding

What is the Slitting and Rewinding Process?

Slitting and rewinding is a precision converting method used to cut large rolls of material into narrower widths and then rewind them onto smaller, more manageable rolls. During rewind slitting, a master roll is unwound and fed through a press, which slits the material to narrower widths. Once slit, the material is rewound onto new cores for use in manufacturing applications or other purposes. Often paired with kiss cutting or rotary die cutting to produce high-quality results, slitting and rewinding are cost-effective methods for creating precision products to custom specifications.

Baloney Roll Slitting Services

Baloney slitting, also known as log slitting, is a shearing process that converts a large master roll into narrow rolls by driving a rotating blade into the log. Once the material is completely slit through the supporting 3" core, the spools are removed from the mandrel. Precision baloney slitting can be used for materials with or without adhesive backing. Key benefits of baloney slitting include:

• Compatible with adhesive and non-adhesive materials
• Ideal for high-volume converting projects
• Supports material widths up to 72"
• Produces precise, repeatable cuts

Slitting and Rewinding FAQs

Why would I need slitting and rewinding services?

Slitting and rewinding converts master rolls into usable widths for production, assembly, packaging, or resale. Rewinding also prepares material for easier handling, equipment compatibility, downstream converting, or direct end-use application.

What materials can you slit and rewind?

Slitting works with a wide range of roll-fed materials, including foams, tapes, adhesives, and thermal materials, but how a material behaves during processing depends on properties like flexibility, thickness, hardness, adhesive construction, surface finish, and roll stability. Some materials require different slitting methods to hold roll quality and consistency. Send us your material spec, and we'll recommend the right approach.

What slit width tolerances can you hold?

Tolerance matters for assembly-line feeding, automated dispensing, downstream converting, and consistent roll performance. Achievable tolerances vary by material type, thickness, adhesive, and roll construction, so our team will confirm exact specs based on your application.

Can you slit and rewind to custom core sizes and roll lengths?

Yes. Core ID, roll OD, and linear footage can often be customized to match your equipment, handling needs, or production requirements. Tell us how the rolls will be used downstream and we'll build the format around it.

What is baloney slitting, and how is it different from rewind slitting?

Baloney slitting, also called log slitting, cuts a full roll or log into narrower rolls in one pass. Rewind slitting typically unwinds a master roll, slits it, and rewinds the material onto new cores as finished rolls. Both processes reduce a large roll to usable widths, but the setup and output differ. Our die cutting services often pair well with slit material for further processing.
