Abstract
Apparatus for producing tufted textile goods employs a plurality of hollow needles which serve as backing openers, the backing openers being carried on a widthwise extending member which is reciprocated in a vertical direction to cause the backing openers to penetrate a backing. Yarn is transported pneumatically through the backing openers and implanted into the backing as yarn turfts, and backing being shifted in the transverse direction by an amount corresponding to the spacing between adjacent backing openers in order to implant a transverse row of tufts. A knife blade is associated with each backing opener and positioned on the opposite side of the backing so as to engage the flat angled surface of the backing opener which forms its pointed tip. The angled surface is formed with an upwardly and inwardly extending slot which serves to capture and center yarn exiting the opening in the angle surface, and which provides a sharp edge which cooperates with the blade for cutting the yarn. The cutting mechanism results in little or no wasted yarn.
