STEWARTS Pinned Perforation Rollers are high precision parts, designed and manufactured in many different variations to meet our customer's requirements for both Hot Needle Perforation and Cold Needle Perforation.
The accurate and uniform pin-point concentricity ensures even perforation from a pin prick to the full pin diameter. The pin-point accuracy makes setting easier and results in more accurate perforation. The smooth, but sharp pin-point produces a clearly defined hole with clean running and little drag.
Self contained modular design.
Free running, driven by the material being perforated .
Quick release cam-operated bearing blocks to disengage the Pinned Roller ensures an accurate return to the original setting.
Easily adjustable perforation depth.
The Bristle Roller can be varied in density and stiffness, Rubber Rollers are also available.
Pin wear is virtually eliminated.
STEWARTS micro perforation rollers are manufactured in a range of materials to suit the customers requirement.
The full range of pinning densities are available on request.
The perforation pins are securely bonded into an aluminium or brass tube using an anaerobic adhesive. This construction is accurate, strong and light weight, and allows for the use of toughened smooth steel pins, with no screw threads required, so there are no sharp edges to collect debris.
The smooth, but sharp pin-point produces a clearly defined hole with clean running and with little drag.
