Abstract:

A baler for compacting fibrous materials or other compactable materials having a platen operable by two compression devices. One compression device is at least one hydraulic cylinder with a piston rod attached to the platen which performs compaction. The other compression device is at least one hydraulic cylinder with a piston rod which is attached to the platen and performs tramping. The apparatus provides rapid tramping before compaction by the selective activation of only the second compression device. Both cylinders function through a common hydraulic fluid reservoir and solenoid valve.

Abstract:

A vacuum cleaning system is disclosed for cleaning the automatic insertion area of a loom. In a typical weaving operation, there are a number of successive rows of individual looms (11). In accordance with the present invention, there is a main vacuum line (28) routed transverse to the rows of looms and secondary vacuum lines (26) extending along the rows of looms. Electropneumatic valves (29) are provided to selectively connect and disconnect the individual secondary lines so that an intermittent vacuum may be placed on the looms of successive rows in a cyclic manner. The vacuum cleaning system includes a vacuum manifold (46) connected by a branch line (40) to a secondary vacuum line (26). A balancing valve (42) is included in each branch line (40) to balance the vacuum at each loom so that generally equal vacuum is applied to the looms along the row. A number of individual, directional lines (A, 72, 74, 76, ) are connected to manifold (46).
