Circular bellows

Characteristics

Made from a core of rigid polyamide fabric with layers of PVC on either side.

These systems are applied to protect spindles, shafts and columns and the optical fibre in laser machines.

Parts of the circular bellows

• A Nylon fabric with layers of PVC.
• B Stitching.
• C Silicon coating.
• D PVC slides.
• E Steel hoop for large bellows.
• F Air outlet holes.
• G Support for fastening bellows to machine.
• H Collar for fastening to the machine.

Opening systems

For very heavy vertical protective elements, tecnifuelle has a number of opening systems:

SYSTEM 1
Stretching device using staples located on the support frame, on as many folds as required, depending on the size of the bellows.

SYSTEM 2
Scissors-type stretching device, ideal for elements that are not guided by the intermediary frames.

Ways of securing ends to the machine

• In the system with steel frames, the anchoring type and anchoring holes must be specified by the customer.
• In systems where Velcro is used to fasten the bellows, one side is joined to the end frame of the bellows and, the other to the frame of the machine.
