Independent Machine Company. Glossary of Terms, Traverse Winders. Designing and manufacturing high quality converting and web-processing machinery

Core - Cylindrical tubes made of paper, cardboard or plastic onto which the material is wound

End Dwell - The amount of degrees the strand stays at the end of core before reversing travel

Flange - Inserted into end of cores to hold certain materials in place on spool

IMC Dancer Tension Controller - Closed loop system for controlling strand tension during spooling

Narrow width Material - Material up to 8" wide

Pitch - Travel distance of material per one revolution of core

Product Guides - Guides material through the process onto core

Roller Guides - Bearing mounted rotating guides

Shoe Guides - Used for guiding materials between flanges

Slit Width - Width of material to be traverse wound. (Also know as strand width)

Spool Diameter - Outside diameter of the finished wound spool

Spool Width - It is the width of the finished spool when traverse wound onto the core

Stroke Length - The total distance of travel across the core before reversing

Traverse Winding - Creation of a wound product into continuous long lengths also known as spooling. The principle is to form a spool by traversing the material across the face of the core in a programmed pattern, reverse its direction, so the material traverses in the opposite direction, thus building layers until a finished spool is created.

Winding Pattern - Traverse movement that determines spool shape

Standard Winding Patterns

Level Wound -

Taper Wound -

Reverse Taper Wound -

Magnum Wound -

Index Wound -

Web Tension - The amount of force or pull on the winding strand
