Abstract
A tri-fold paperband of paperboard having two side portions folded across a center portion in overlapping manner to form a three layer middle portion, the side portions being of a width greater than half of the width of the center portion but of lesser width than the center portion, such that the side portions overlap, and such that two flexible lateral portions are defined having only two layers.
Claims19
A tri-fold paperband composed of folded paperboard and suitable for use in paper web cutting, turn-up systems and baling, said paperband comprising:
- a paperboard having side portions, a center portion and edges, said side portions being folded inwardly onto a center portion, the width of said side portions being less than the width of said center portion but greater than half the width of the center portion, such that said side portions overlap each other but do not extend completely across said center portion, thereby defining a middle three layer portion and a pair of lateral portions having only two layers;
- said side portions and said center portion being adhesively joined;
- whereby two longitudinal flexible joints are defined adjacent said edges such that said lateral portions readily flex relative to said middle three layer portion.
A tri-fold paperband composed of folded paperboard and suitable for use in paper web cutting, turn-up systems and baling, said paperband comprising:
- a paperboard having side portions, a center portion and edges, said side portions being folded inwardly onto a center portion, the width of said side portions being less than the width of said center portion but greater than half the width of the center portion, such that said side portions overlap each other but do not extend completely across said center portion, thereby defining a middle three layer portion and a pair of planar lateral portions having only two layers;
- whereby two longitudinal flexible joints are defined adjacent said edges such that said planar lateral portions readily flex in a hinge-like manner relative to said middle three layer portion.
A tri-fold paperband composed of folded paperboard and suitable for use in paper web cutting, turn-up systems and baling wherein said paperband is pulled from a track assembly, said paperband comprising:
- a paperboard having side portions, a center portion and edges, said side portions being folded inwardly onto a center portion, the width of said side portions being less than the width of said center portion but greater than half the width of the center portion, such that said side portions overlap each other but do not extend completely across said center portion, thereby defining a middle three layer portion and a pair of planar lateral portions having only two layers;
- whereby two longitudinal flexible joints are defined adjacent said edges such that said planar lateral portions readily flex in a hinge-like manner relative to said middle three layer portion when said paperband is pulled from a track assembly.
