Abstract: The invention relates to a crusher unit that can be transported directly on roadways, the crusher being mounted on an elongated, rigid frame which is supported by several travel mechanisms or support trestles which rest directly on the ground underneath. The frame has several hydraulic jacks which are adjustable in height and lift the travel mechanisms or support trestles from the ground when the jacks are extended. In order to reduce the height of this crusher unit during transportation, the invention proposes that the travel mechanisms or support trestles be removed for transportation. This is achieved by means of quick-release fastening mechanisms and by arranging and dimensioning the jacks such that there is sufficient room under the frame to drive a transport vehicle which can be used on roadways.

Abstract: A pair of specially designed suction wheels are preferably placed after the glue applicator on a known pinch bottomer bag-making machine. During manufacture, paper bags are guided horizontally through the machine by a conveyor forming part of the machine. With this arrangement, one of the suction wheels is placed under the bag, and the other wheel is placed over the bag in line. As each bag is moved by the conveyor, both suction wheels are brought into motion like a rolling operation. Each wheel has a shaft with a hollow channel going to a suction cup at the periphery of the wheel. The number of suction cups around the circumference of the wheel could be any amount. In a preferred embodiment, there are 12 equally spaced suction cups. A vacuum pump with a hose is connected onto the shaft. The pump draws air through the channel which comes from a suction cup so that, when the bag comes into the vicinity of the suction cup, the cup sticks on the bag layer.
