Abstract: A separation layer (12) for laying grass surfaces (10; 16) on a sand or gravel base (13), which layer is in the form of a rigid plastic sheeting with parallel side edges. The surface of the sheeting is embossed by thermo-forming so that it presents a uniform pattern of deep embossings (14). These form rows which extend perpendicular to said side edges. The parallel rows are each connected to adjacent embossings in the same row via bridges (15) so that each row of embossings in cooperation with adjacent rows creates a stiffening of the sheeting.

Abstract: A box for storing and dispensing food-stuff distributed upon a foil band and wound to a spool upon a shaft comprises two like components, each defined by a base plate and three adjoining walls. Each wall is provided with an open slot starting from the edge of the pertaining wall remote from the base plate and extending about half-way down towards the latter, whereby the two components become sufficiently deformable to permit a fitting together, to form either a closed box, or a stand presenting an open front for serving-out purposes.The slots in two oppositely located walls are formed to carry the ends of the shaft and the slot in the intermediate wall preferably is deeper than the slots in the first mentioned walls.A box of this type may be fitted in an apparatus having a rotatable drum for coiling up the wasted foil band, as this is pulled out of the spool, to make the food-stuff available.

Abstract: A device for maintaining a tensioning in an elongate strip of plastics, when transferring the latter from one station to an other, located to opposite sides of a machine distributing slices of foodstuff upon the strip, includes, at the first station, a dispensing device arranged in conjunction to a strip storage roller, and provided with a pivotably suspended, motor-driven feed roller cooperating with a pinch roller. The second station comprises a shaft adapted to carry at least one tubular core for receiving the strip and is driven by a motor by way of a slipping clutch, which permits a somewhat higher speed than that of the feed roller at the first station.The shaft is preferably designed to carry two tubular cores, and extends cantileverwise from a bearing device. A hub receiving an inward core encloses and carries, together with a driving pinion, part of the shaft, the pinion being mounted upon a trunnion which, in turn, is journalled in the bearing device.
