US Patent 3,757,740 (granted 11 Sept 1973) to Gabriele Peressini of Udine, Italy, describing an artificial silkworm cocoonery and a machine for removing the cocoons. The cocoonery consists of shafts fitted with sleeves that carry semicircular sets of flexible plastic spokes, alternated so the spokes interleave, giving a hygienic surface on which the worms spin. A rotating drum holds the cocoonery units against a pivoting comb whose teeth dislodge the cocoons into a collecting bin. The patent includes the abstract, two sheets of drawings, a description with dimensions and operating speeds, and 16 claims.
