Product Name: Pneumatic locking bearing for dyed beam rolls

Product Description

Winding or unwinding of dyed beam rolls often poses problems of motorisation due to the absence of a fixed axis. The "Machines Coopelin" locking bearing permits the resolution of this particularity by capturing the lower part of the beam roll between three points. This bearing is constituted by two carter rollers and an internal roller. The concept which is quite simple in appearance, is nevertheless very sophisticated because of the absolute security imperatives, the dimensional imperfections of beam rolls (eccentricity), the necessity to disengage the upper line level of the roll especially for winding where the presence of a cylinder press turns to be generally indispensable. This bearing regroups all the qualities required and is of a very robust design. Technical Characteristics - Can take beam rolls of 400 to 600 mm diameter standard. - Pneumatic logics. - Pressure of internal roller > 300 daN. - Pneumatic security liaison (return to the motorisation). - Presence detection of beam roll by measurement of the pressure on the internal roller. - Detection of locking operation; if locking activated, autorisation is given to the motorisation for establishment of the drive couple. - Absorbtion of eccentricity of the beam roll to 10%. - Permits transportation of beam rolls from one point to another in security (air disconnected). - In the case of accidental or voluntary abscence of air or, beam roll trapped in the mechanism and instant halt of the motorisation (or start-up is blocked) by surveying return air pressure on pneumatic logics. - Equipment entirely pneumatic. - Easily assembled on various existing carriages. - Version possible with motorised internal roller (on option). - Standard colour RAL 5002.
