straight heat-welded bellows Made from a core of rigid polyamide fabric with layers of PVC on either side. Opaque black material between, 0,25 and 0,4 mm. thick. Rigid PVC supports in each fold, which are welded to the polyamide fabric on high frequency machines. These rigid supports come in thicknesses of 0.8 mm. in white, 1 and 1,5 mm. in grey. For specific cases, TECNIFUELLE bellows may include polyurethane slides joined to the rigid PVC framework to prevent unwanted noise and improve internal sliding. Depending on the width and length of the protectitve cover, they may also include stretching...

1 Pleated protective nylon cloth with PVC coating on either side. 2 Intermediary PVC stretch frames. These frames provide the rigid aperture for each fold in the covering, ensuring that it is safely guided along the sliding plane 3 Join between the folds and the intermediate PVC frames, using highfrequency welding. 4 Metal frames for securing the bellows to the machine 5 Intermediary slides _straight bellows. construction types and characteristics opening systems For very heavy vertical protective elements, TECNIFUELLE has a number of opening systems SYSTEM 1.- Stretching device using staples...

Made from a core of rigid polyamide fabric with layers of PVC on either side. Opaque black material with thicknesses of 0,4, 0,6 and 0,8 mm for temperatures of up 70°C. Where temperatures of over 70°C occur, fibreglass plus 0,47 mm Viton, and kewlar fibres plus PU with a thickness of 0,36 mm are used. These systems are applied to protect spindles, shafts and columns and the optical fibre in laser machines. rts of the circular bellows A Nylon fabric with layers of PVC ^ Stitching 3 Silicon coating ^ PVC slides ^ Steel hoop for large bellows J Air outlet holes G Support for fastening bellows to...
