Abstract: A vehicle for transporting, rolling and unrolling ground covers broadly includes an elongate framework, a spindle supported by the framework to mount one or more rolls of material, one or more ground wheels, and split bearings located toward the ends of the framework for receiving and supporting the roll-carrying spindles. The split bearings each include an upper part which is openable to enable the split bearing to receive and secure the end of the spindle. Preferably, the framework includes one or more parts, such as support members, which are operable to pivot about the framework so that the angle of the axis of the spindle is adjustable.

Abstract: This invention is directed to improvements in paper incorporating a wide elongate impermeable element, to a method of making such paper and to documents made therefrom. The method comprises the steps of first bringing an elongate, flexible, impermeable element into contact with a support surface prior to their entry into a vat of aqueous paper stock, then depositing fibres onto the support surface to form paper. The element has a width of at least 6 mm and the deposition of fibres is carried out in such a manner that as fibres are deposited on the support surface the elongate element is incorporated in the paper with regions of the element at least partially exposed at least one surface of the paper at least two sets of windows at spaced locations. The at least two sets of windows are formed by two sets of portions which are raised from the support surface relative to adjacent areas of the support surface.
