The door is fashioned of a pair of spaced apart panels which form respectively one side of the door and the other side of the door.

Abstract: A worktable comprises upper and lower members that fit together in sliding relation with a rectangular extension of the upper member protruding into a recess in the lower member. The recess is larger than the extension so as to permit the upper member to slide across the surface between the upper and lower members. Eight adjustment screws are mounted in opposing pairs in the lower member so that each pair bears on a different side of the extension. By backing off on some screws while advancing others, the upper member of the worktable may be moved with respect to the lower member to adjust the position of the workpiece with respect to the grinding wheel. The use of pairs of opposing adjustment screws permit both rectilinear movement of the upper member depending on the amount of advancement of each pair of screws and rotational movement when the screws in each pair are advanced by different amounts.

Abstract: The present invention is directed to a method and apparatus for packing tubular bags into boxes by machinery. The tubular bags to be packed are conveyed over various conveyor belts to a positioning belt and from the positioning belt to a positioning table. Layers of tubular bags are then moved onto a rake-like main base that is lowered in a stepwise fashion to receive consecutive layers of tubular bags. When the desired number of tubular bag layers is positioned on the main base, the main base is lowered to deposit the tubular bags onto an intermediate base which together with side walls makes up an intermediate container. Once the intermediate container is in a lower position, a box is pushed over the intermediate container and the intermediate container is swung through a 90.degree. arc onto a conveyor belt. The intermediate container is then removed from the box and by this process the tubular bags which were previously in the intermediate container are transferred into the box.
