Abstract: A two-wire former for producing a web of fibrous material, in particular a paper web, is designed as a gap-former with the following characteristics: a first and a second wires form together a twin wire; a headbox injects the pulp directly between the two wires; at least one first dewatering zone consists in the advance direction of a curved, non-rotary, interrupted surface, for example a forming shoe or several strips that form together a surface. The invention is characterized in that a convex dewatering element that starts directly at the point of impact of the jet of pulp is provided at the beginning of the first dewatering zone, seen in the advance direction, and has at least two curvature radii Ri in contact with the wires. Both curvature radii Ri are smaller than the curvature radius Ri+l that follows them in the advance direction.

Abstract: A shrink wrap or stretch wrap pallet system including a pair of end panels arranged and configured so as to mount on opposite sides of a package, effectively connecting a base pallet and a top panel. The end panels themselves are spaced from the perimeter of the package. The end panels have vertical edges which extend beyond the perimeter of the package, thereby defining a plane between respective end panels, the plane serving to space the wrap, which lies substantially therein, from the package. The end panels are conveniently sized and shaped to fit within the area of the base pallet, intermediate panels and top panel thereby providing a relatively compact return package. Side panels may be provided to supplement the end panels.
