Abstract: An apparatus for stopping and resetting a loom. The technical problem which lies at the foundation of the present invention is to provide an apparatus for stopping and resetting a loom to a certain position before a weft stroke which has given an indication of breakage. This technical problem is solved according to the present invention in that a weft fork which senses the weft, and, in the event of a predetermined breakage type in the movement of the weft during a sensing period emits a signal for stopping the loom, is arranged to prevent gripping of a new weft after the generation of a breakage signal, whereby the rapier or rapiers execute one or more strokes without a weft.

Abstract: A handtool (1,2) for threading e.g. a weft yarn in a pneumatic weaving machine has a conduit (8,9) issuing therefrom, the free end of which constituting a blowing nozzle (9).

The yarn is presented to the guiding surface (3) of the tool whereafter it is carried along by the air jet of the blowing nozzle (9). In one embodiment the tool has a thread guiding eye (4) with a lateral release slot (5).

Abstract: An oil spraying pump having a piston which is stationary with respect to a movable cylinder having a discharge opening therein. A normally sealed bore-hole extends through the piston from the cylinder interior to atmosphere. Means are provided to supply oil to the cylinder interior whereby when the bore-hole is sealed, relative movement between the cylinder and the piston causes oil to be sprayed from the discharge opening.
