A. Flange Use proper thickness of plate to fix at both sides or the protective curtain or the punched stiffener, and the  other side should be fixed at the guide way. Normally a SPCC sheet metal is applied. Upon customer’s request, any shape, thickness, other metal or mounting method are available.

B. Stiffener The stiffener is a PVC board (meet the RoHS) that provides a support for the inside of a protective curtain. It’s not only to reduce the contact between the protective curtain and the slideway, but also to provide a solid support, rigidity and impact-resistance. The stiffener is made from wear-resistant plastic with self-lubrication feature. The availavle thickness is 0.5 / 0.8 / 1.0 / 1.5 / 2.0 mm. Note : the increased thickness of stiffener may affect the compressed size of the protective curtain.

C. Protective Curtain The standard material of protective curtain is a black eco-friendly material coated with PUR at both sides. It features long service life. When requested, a single side with yellow or white color is available. The protective curtain and stiffener are welded securely without sewing lines or holes. It features excellent water-resistance and oil-resistance. The material thickness of the protective curtain may vary with customers’ environmental temperature, machining condition and chemical reaction.

Restricted beltThe restricted belt is necessary to prevent over-extending of corrugation, and suitable for fast moving speed, vertical movement or large-scale protective curtain. The Panerai Replica additional restricted belt is fitted for the protective curtain used in a closed, confined space for extending the service life of protective curtain.
