Shafts with Clamping Shells
Positive fit along the entire core length: clamping shells accommodate thin and delicate cores without deformation. Precise concentricity, strong in multi-reel operation.
Shafts with clamping shells are the correct choice when delicate cores and high winding quality are required. Instead of gripping at specific points, the continuous clamping shells apply pressure over a large area to the core inner diameter. This prevents deformation of thin-walled material and creates an almost circular clamping pattern. This allows narrow rolls to be reliably processed in multi-reel operation and contact rollers to be easily applied.
Whether pneumatically, mechanically-centrically, or tensioned via permanently applied spring force: the best design depends on your concentricity requirements and your loading concept. The following five series cover the most common requirements.
