Stretching system (Stretcher) provides the necessary tension to Fabric with a controlled movement of a roll called tension roll.

Keeping constant tension means:

• paper quality optimization;
• sheet break reduction;
• increased Fabric life;
• avoid fabric overstretching;
• avoid drive roll slippage.

Stretcher is also in charge of long stroke roll displacement during fabric change operations.

WIRE ARMS STRETCHERS, with rotational movement: tension roll moves through arms operated by air rides or pneumatic cylinders. Wire tension is proportional to air pressure. Pneumatic system allows continuous tension compensation.

FELT STRETCHER FOR PRESS OR DRY END, with linear movement of tension roll support carriages. We can propose different stretcher designs: SCREW JACK STRETCHER, where carriages move driven by a rotating screw jack system; PNEUMATIC COMPENSATED SCREW JACK STRETCHER where a couple of air cylinders keep constant tension. Tension roll stroke is adapted to wire or felt length and to available room. Models with electric, hydraulic or pneumatic motor available.
