Abstract: This relates to an abrasive cleaning machine wherein there is mounted within a suitable frame or housing a work supporting conveyor which is mounted for both reciprocatory and rotational movement. When the conveyor is in the form of a rocker barrel, the rocker barrel is only oscillated. On the other hand, when the conveyor is in the form of a cage-like conveyor, the conveyor is continuously rotated. The principal feature is the mounting of the conveyor for such rotary and reciprocating movement. This includs a support structure in the form of a support sleeve mounted for rotation and a support shaft mounted within the support sleeve for relative reciprocatory movement. The support shaft carries a pair of longitudinal ribs which are engaged by rollers carried by the support sleeve to transmit rotational movement from the support sleeve to the support shaft. Thus the supporting of the conveyor is simplified.

Abstract: An improved paper guide device is disposed close to folding rollers in a folding machine of a rotary press as spaced from an outer circumference of a folding drum. During normal operation, the paper guide device is preset to allow for minute movement of the folding rollers during the folding operation. But when the folding rollers clog with paper and move apart beyond a predetermined distance, the paper guide device moves as interlocked with the folding rollers. Therefore, paper guides of the paper guide device never contact the folding rollers. Preferably, the position of the paper guides relative to the folding rollers can be changed such that the widths of the respective gaps between the paper guides and the folding rollers can be adjusted.

Abstract: A container and method of making the same preferably from a single web of flexible material wherein the method comprises placing a V-fold, or modified flat V-fold, in a sheet of such material, creating two subsections whose V-fold members are attached to the respective subsections preferably along a longitudinal fold line. First and second side edge weld lines are made thereby connecting the respective subsections to their own V-fold members as well as those of the opposite subsections. Oblique weld lines then interconnect the point of intersection of the side edge weld lines and longitudinal fold line. The bottom wall is formed by folding the legs inwardly with the endmost portions of which pivoting along a lateral axis of the bottom wall upwardly towards the first and second side edge weld line thereby reinforcing the stress-bearing bottom.

Abstract: In accordance with illustrative embodiments of the present invention, a hopper containing a sodium bicarbonate abrasive is pressurized with a dry gas such as nitrogen. The abrasive is fed into a transport line through which compressed air flows toward a nozzle, and pressures in the hopper and transport line are regulated so that the hopper pressure is greater than the transport line pressure by an amount that keeps the abrasive in the hopper very dry so that the same differential pressure causes a precisely metered amount of abrasive flow.Another aspect of the invention relates to a method of cleaning by applying a stream of dry water soluble abrasive particles, such as sodium bicarbonate particles, entrained in air, as the abrasive agent to a cavity of a blast nozzle to which water under pressure is also applied. Such method includes the step of directing the output of the nozzle toward a surface to be cleaned.
