Tufting machine
First Claim
Patent Images
1. A tufting machine comprising;
- a plurality of aligned needles arranged to reciprocate in a direction which, in use, is perpendicular to a backing material which is progressively fed through the machine;
a hook associated with each needle which is oscillatedly moveable, in use, to pick up yarn from its associated needle, a loop engaging surface of the hook being below the backing material;
wherein each tuft is isolated from a tuft formed by an adjacent needle by a divider plate which extends in the direction of needle reciprocation for at least 20% of the distance between the backing material and the loop engaging surface of the hooks with each divider plate extending from at least one of reed fingers of a needle plate and a support block connected to a bed plate located below the needle plate.

Abstract
A tufting machine for producing pile fabric having a pile height of approximately at least 50 mm has divider plates between adjacent needles to prevent yarn loops and especially the legs of cut loops from becoming trapped between an adjacent needle and its associated yarn feed. The divider plates may take the form of plates forming an extension of the fingers of the needle plate between each pair of which a needle reciprocates and may be mounted on a block on the bed plate beneath the needle plate, or may be plates upstanding from the hook bar.
