Abstract: A hoop for holding a piece of textile and a backing web for embroidery on the textile piece comprises outer, intermediate and inner rings. The outer ring is generally rigid, formed of a limitedly elastically deformable synthetic resin, and has a generally polygonal inner periphery generally centered on an axis. The intermediate ring is formed of a limitedly elastically deformable synthetic resin and has an outer periphery generally complementary to and axially fittable with limited play within the inner periphery of the outer ring and a generally polygonal inner periphery. Thus the intermediate ring can be elastically deformed and snapped into the outer ring with the backing web gripped between the inner periphery of the outer ring and the outer periphery of the intermediate ring. The inner ring is formed of a limitedly elastically deformable synthetic resin and has an outer periphery generally complementary to and axially fittable with the limited play within the inner periphery of the intermediate ring.

Abstract: A device for depositing an electrifiable material, e.g. cut strands, fleece, flock, upon an adhesive-coated surface comprises a vibrating sieve which is formed by a multiplicity of cylindrical parallel elements in line contact along respective generatrices and in line contact with an enclosure. In the interstices between these elements the electrifiable material passes through a grid on the bottom of this sieve which is connected to a high voltage source so that electrostatic forces assist in a transfer of the material to the adhesive. The application pattern is determined by a mask on the upper portion of the sieve and a complementary mask on a similar sieve through which excess particles are evacuated from the application region.
