The pile warp beam is placed below the ground warp beam and a tensioning beam is positioned to guide the pile warps into the weaving plane so that access can be made to the machine by moving the ground warps aside without pulling out the beat-up pile loops. A deflecting means also cooperates with the tensioning beam to guide the pile warps about 180* around the tensioning beam.

The rail vehicle which is supported on three bogies is provided with spring suspension systems for each bogie. A primary suspension system supports each bogie on at least a pair of drive axles and secondary suspension systems support the vehicle chassis on the bogies. The combined spring constant of the suspension systems for the middle bogie is made softer, or less than, the combined spring constants for the outer bogies to equalize the load relief on the two forward bogies during travel.

The pile warp threads are passed through a storage means including a movable deflecting beam and two fixed bars which serve to form a thread reserve between two full beat-ups of the loom. A clamping beam cooperates with the bar of the storage means closest to the shed to clamp the threads during the time intervals between two successive beat-ups or between successive full and partial beat-ups. The opening of the clamping beam occurs simultaneously with the release of the thread reserve from the storage means to allow delivery of the pile warp threads without tension to the shed. This obviates any backward pull-out of the formed loop in the cloth.

The irradiation plant can be used to treat various flowable materials including effluent or sewage sludge. The plant contains a concrete vessel in which a partition is mounted to form two coaxial irradiation chambers through which the flowable material can be circulated by means of an impeller. The partition can be formed to house tubes of radiation sources and to provide a venturi-like member about the impeller. The operation of the impeller is reversed periodically to assure movement of both heavy and light particles in the flow.

The lifting hook is provided with a pair of intermediately positioned hooks which enable coupling of the lifting hook to one or the other of the draw knives. The lifting hook has a retaining hook at the upper end to engage a claw on the support and either a similar hook to engage a claw on the lower edge of the support or a stop plate for engaging an apertured board through which the lifting hook passes. The intermediate hook on the same side as the retaining hook at the upper end of the lifting hook is longer than the opposite knife engaging hook.

The speed of the warp feed roller is controlled in dependence on the warp tension in the weaving machine via a control motor. The speed of the motor is regulated by signals obtained from a pressure sensor on the breast beam which sensor measures the pressure of the produced cloth on the breast beam. The control signals can also be obtained from a measurement of the rate of cloth draw-off. Alternatively, a torque pick-off can be used to measure cloth tension in order to produce the control signal for the control motor.

The movable guide element for forming the yarn reserve in the weft yarn path is provided with a driven guide roller over which the weft yarn moves. The guide roller is positively rotated in the direction of yarn movement at a speed at least equal to the yarn speed to reduce the tension in the weft yarn and, thus, to reduce the power needed for picking of the weft yarn into the shed.

The component warp beams are each provided with a blocking means in order to temporarily lock the warp beams during the reed beatup portion of the machine cycle. The blocking means includes hydraulically actuated brake heads for engaging a brake disc on each warp beam or a warp beam gear for controlling the let-off motion of a warp beam. The blocking means can also include an electrically operated brake.

The control valve is controlled in dependence on the pressure condition of the fluid flowing into the valve inlet. The valve closure member is under a biasing force independent of the electric motor to be moved into an open end position. In addition, the motor provides a force opposed to the biasing force to keep the valve closed. In order to release the closure member, the effect of the motor on the closure member is controlled via a switch, clutch or brake so that upon an increase in pressure over a set limit in the line to the valve, the closure member becomes biased into the open position.

The severing roller is caused to roll on the support while also rotating during a severing operation. After severing, the roller and support are moved apart. The severing surface of the roll can thus be given a longer life. Drive means are provided to effect the translation movement of the roller. The support can be in the form of a resilient cam and can be moved into the path of the roller during severing to increase the severing forces.
