HCI QUICK-LOCK RINGDIFFERENTIAL SHAFTFRICTION RING
The HCI Converting Equipment HCI Quick-Lock Ring is a patented (PATENT NO. 186461) solution developed by HCI for the differential shaft (differential shaft) and friction ring system. On slitter and rewinding machines it manages various torque combinations between the differential shaft and the friction ring; it provides consistent rewinding tension for each reel. Winding speed differences are eliminated and uniform tension is produced per reel. It makes paper core replacement practical without scratching and offers the convenience of an air shaft. It can be retrofitted onto new or used slitter/rewinder machines without harming the original structure. The ball type friction ring variant is offered optionally on the HCI Slitting Machine. GMG Technic Makina San. ve Tic. Ltd. Şti., as the HCI Converting Equipment Türkiye distributor, manages the sales, technical support and installation processes.

Detailed Features
HCI Quick-Lock Ring — technical documentation
HCI Patented Design
PATENT NO. 186461 — HCI in-house developed differential shaft + friction ring technology.
Quick Lock Mechanism
Fast paper core grip; air shaft convenience; setup time is reduced.
Damage-Free Core Replacement
Scratch-free core replacement; core life is extended.
Uniform Reel Tension
Management of various torque between the differential shaft + friction ring; uniform tension.
Winding Speed Difference Elimination
Reel winding speed differences are managed; consistent tension for each reel.
Retrofit Compatibility
Retrofit onto new or used slitter/rewinder machines.
Original Structure Preserved
