Abstract: A defibrator which makes it possible to distribute defibrated cellulosic fibers directly onto a forming wire (5) includes ribs (33) extending inside a cylindrical housing (24). The ribs have outer curved surfaces which direct fibers into an area (35) in which beater plates (25). A grate (37) in front of an outlet (30) from the circular housing (24) is arranged at the periphery (35) for the rotation of the beater plates (25). The grate has an interspace between grate bars only allowing fibers to pass through. Accordingly, agglomerates are returned into the working area of the beater plates (25). As the beater plates (25) act several times on agglomerates, it is ensured that only individual fibers pass through the grate (37). Accordingly, fibers are discharged directly onto the forming wire (5) from a discharge opening (2) of the defibrator (1). Preferably, the discharge opening (2) has a width corresponding to the width of the product to be formed on the forming wire (5).

Abstract: A machine for sewing a binding tape to a cut edge of carpeting comprises a wheel-mounted sewing machine having an opposed pair of pinch rollers engaging opposed sides of the carpeting, the pinch rollers being inset from the cut edge and one of the rollers being intermittently motor driven in synchronism with the reciprocating movement of the sewing machine's needle assembly. As the one pinch roller is driven, the sewing machine moves along the floor as the binding tape is played from a reel, folded longitudinally and stitched to the carpet edge. The machine incorporates a spring-biased needle guide which effectively surrounds the needle shank as it moves reciprocally up and down to create the stitches. This guide prevents deflection of the needle and possible breakage thereof should it encounter a hard object, such as a glue bead or the like in the carpet backing.

Abstract: The traditional feed plate or stationary feed bar of a lint cleaner in a cotton gin is replaced by a rolling feed bar to press the cotton fibers onto the saw teeth of the saw cylinder. A rolling feed bar is a cylinder of about 1/4 the diameter of the saw cylinder which is rotated to have a surface speed of about 1/25th (+ or -50%) of the surface speed of the saw cylinder. The rolling feed bar is a smooth aluminum roller which co-acts with a ribbed or splined steel roller.

Abstract: An apparatus for automatically and simultaneously ironing front, rear and top portions of a shirt comprises two vertical movable ironing plates therebetween there is provided a dummy bearing a shirt to be ironed, the dummy including an upwardly movable top portion and the ironing plates having two concave top seats negatively reproducing the profile of the top of the dummy, the apparatus further comprising gripping elements to automatically grip and transfer the ironed shirt.
