The endless pocket strip has pockets in pairs alongside each other, partic. for films etc., and comprising two strips glued together to form the front and rear, together with windows covered by transparent panels. Both the front and the rear of the pockets have opposite windows, while the transparent material consists of two strips passed over the windows at the front and rear of the adjacent pocket and glued along the window edges. These strips are joined together by a glue seam in the centre, where the edges of the adjacent pocket join. |
