A weaving machine for the manufacture of leno cloths includes a leno apparatus with leno elements (5, 5null, 7, 7null, 8, 8null) for the forming of a shed (6) as well as additionally a cleaning apparatus with a plurality of nozzles (10.1, 10.2, 11, 13) for the removal of contaminations in the region of the leno apparatus and of the shed (6). Two of the nozzles (10.1, 10.2) are arranged above the shed, by means of which a compressed air flow (16.1-16.4) which is directed downwardly through the shed (6) from above is produced, and one of the nozzles (11) is arranged in the lower region of the leno elements, by means of which a compressed air flow (17) which is directed substantially horizontally towards the leno elements (5, 5null, 7, 7null, 8, 8null) is produced. In addition, a suction nozzle (13) by means of which a downwardly directed suction air flow (19) is produced is arranged beneath the shed.

Gas flows, whose plurality of conditions are controlled by modular environmental control apparatus, are sourced to or captured from various critical zones in materials processing machines, or in related personnel zones. A plurality of processing performance parameters, part of which may respond differently to environmental conditions in one or more process zones, and thus may be in conflict with each other, are jointly optimized to yield maximum gross profit, to produce highest quality, to operate at highest throughput, etc, (but not necessarily simultaneously). The principal embodiments herein disclosed are directed toward modular process zone and personnel zone environmental control in textile processing machines, in fiber, yarn or fabric manufacturing processes, but the method is very basic and powerful, and those skilled in the art will recognize the applicability to materials processing in general.

A gripper drive for a rapier loom is cooled by enclosing the gripper drive with a cooling medium flow guide housing and passing a cooling medium, such as conditioned air, through said guide housing so that a cooling medium flow must pass said gripper drive in heat exchange contact therewith. The cooling medium is either a suction medium or a pressurized medium and passes through a flow port and slots or openings in the flow guide housing.

A process for the air conditioning of a weaving machine includes generating, for the weaving machine, at least one conditioning air stream spaced from a warp of the weaving machine and directed towards the warp, and distributing the conditioning air stream in stages so as to form a downwardly directed displacement-type flow towards threads of the warp. The displacement-type flow is a non-turbulent, uniform flow over a cross-sectional profile of the flow.

A gripper loom with pneumatic gripper cleaning apparatus is outfitted with at least one gripper associated with a blowing nozzle outside of the weaving area. The blowing nozzle is associated with a suction nozzle on the opposite side of the gripper. The gripper is constructed in such a way that it allows air to pass from the blowing nozzle to the suction nozzle. This enables an intensive and complete cleaning of the gripper and prevents soiling of other structural component parts.

The travelling cleaner for looms and such machines with rows of moving machine members comprises a compressed-air blower guided to and fro along the row of moving machine members, the compressed-air blower is disposed on a compressed-air linear motor which is movable to and fro along a guide attached to the loom supporting the row of moving loom members, and the compressed-air blower and the compressed-air linear motor are connected to a mutual compressed-air source. This renders possible for the first time, a fully-automatic, optimal cleaning of rows of moving loom or machine members on any desired loom or machine of this kind.

An apparatus to clean the reeds of a weaving machine without removing the reeds from the machine and without disconnecting the warp yarns. A cleaning head is slid down the reed and blows a foaming agent from one of the cavities through the space between the dents into the other of the cavities of the reed and sucks the lint, dust, etc. dislodged by the foaming agent back through the spaces between the dents and directs such to a point of collection.

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). The directional loom vacuum lines are flexible and may be moved to a desired location with the free ends of the directional lines unsupported. In this manner the directional lines may be flexed to and away from the vacuum location while rigidly set at the location. A primary loom vacuum line (80) is directed to a mechanical weft inserting device which inserts the weft thread into a projectile (71). The flexible, directional lines (72, 74, 76) are positioned at various thread guides and thread tensioning guides in the automatic weft insertion area to vacuum the loose fly created by the friction of the weft thread passing through the guides.

The air discharge device is constructed with a continuously rotating body to cause periodic unilateral deflections of the discharge stream of air. An "air broom" effect is created which serves to clean the work stations of a weaving machines. Fiber material can be removed from the weaving machine by the air discharge device without requiring any special control of the air feed.

To prevent the accumulation of contaminating matter in the harness of a Jacquard weaving machine, a perforated box is provided at the lower end of the harness. Air is supplied into the box so that it flows vertically upwardly along the harness members and prevents dust, fibers and other contaminating matter from settling on the harness.
