A machine for producing cork discs, particularly for composite stoppers

摘要

The machine comprises a stationary structure (10) and a rotary structure (12). One of these structures (10) has at least one driven, rotary, circular blade (18) and the other structure (12) comprises one or more supply ducts (76) in which a series of cork stoppers or other cylindrical cork elements progress in succession. Pincer means (88) are associated with the opening of the or each supply duct (76). The pincer means (88) are operated in synchronism with the rotation of the rotary structure (12) on each occasion in order to hold the first cylindrical element of the series whilst it is cut by the circular blade (18) and to release the element after the cutting has been performed and before the next cutting operation so that the portion of the cylindrical element which has not yet been cut progresses until it engages a support track for the cutting of a subsequent disc. <IMAGE>
