Abstract: A feed device for feeding yarn or other textile material, the device comprising a hollow member through the interior of which textile material may be passed, feed means for feeding the textile material to the said interior, reciprocating means for reciprocating the hollow member towards and away from the feed means, fluid jet means for directing at least one fluid jet onto the textile material being fed to the hollow member so as to tension the said textile material, and pressure supply means which are arranged to supply a pressure fluid to the said interior to entrain the textile material therethrough during a predetermined portion only of the reciprocation of the hollow member, the pressure supply means also supplying the fluid jet means with an intermittently varying fluid pressure which is respectively reduced and increased, so as to reduce and increase the said tension, in accordance with whether or not the textile material is being entrained through the said interior.
Abstract: A machine for producing a textile product, the machine having a needle provided with a leading end portion which extends non-axially with respect to the main portion of the needle, means for reciprocating the needle, in a predetermined needle reciprocation stroke, into and out of backing material and for effecting relative traversing movement therebetween, and means for ensuring that the leading end portion is inclined away from the direction of the said relative traversing movement throughout the latter, the said leading end portion having an axial length at least as great at the length of the needle reciprocation stroke.
Abstract: This invention concerns a machine for making a textile product comprising a needle carrier shaft, reciprocation means for reciprocating said shaft, yarn feeding means for feeding yarn to a needle carried by said shaft, and control means for ensuring that the needle carrier shaft can be stopped only at an end of its reciprocation.
