In Sigma's frame feeding system, the normal cauls have been replaced by a rigid frame of spring steel around the screen, which is itself suspended between the endbars of the frame at both ends. The design offers severval important benefits:

Frame feeding system

• Reduced weight
• Improved heat transfer
• No caul plate thickness variation
• Optimum use of press daylight openings
• Shorter press time
• Less maintenance

The frame feeding system is suitable for installation in both new and existing production lines, provided that in the latter case the space between the heating plate and the columns is not less than 110 mm.
