发明名称 MACCHINA PER LA TRASFORMAZIONE DELLA CARTA CON CILINDRI GOFFRATORI COOPERANTI PER L'ACCOPPIAMENTO PUNTA-PUNTA DI DUE NASTRI DI CARTA DA ESSI GOFFRATI
摘要 The web embossing machine of the present invention has two embossing cylinders (3, 5) brought close to one another for combining two paper webs (N3, N5) by the pressure contact between mutually corresponding protrusions (S) on the two cylindrical surfaces. The protrusions are in rows which present a pattern inclined relative to the axes (X-X) of the respective cylindrical surfaces, i.e., in a helicoidal fashion and relative to a plane passing at right angle through said axis, and thus achieve a subsequent and progressive contact instead of a simultaneous contact throughout the row. The inclination relative to a plane passing at right angle through the cylinder axis avoids repetitive pressure actions on the pressure rollers cooperating with the embossing cylinders.
