Method and device for the separation of tubes

A method of separating tubes which are produced continuously on a row of mandrels, continuously coupled to one another, by the mandrels being advanced in a conveying direction (X) and by material layers being applied to the mandrels, there being a material difference from the mandrel material at a connection point of successive mandrels, the steps comprising:

• detecting the connection point of the successive mandrels, positioning a cutting head of a separating device for cutting the tube to length wherein the cutting head is aligned with the detected connection point, advancing of the separating device in the conveying direction (X) synchronously with the advancing speed of the mandrels, rotating of the cutting head about the circumference of the connection point for the circumferential cutting of the tube while the separating device is advanced, and withdrawing of the separating device to an initial position after completion of the cutting operation.

A method of separating tubes comprising the steps of:

• continuously supplying material on successive mandrels continuously coupled to one another to form the tubes;
• detecting a connection point of the successive mandrels, aligning a cutting head for cutting with the detected connection point, advancing the cutting head in a conveying direction (X) synchronously with advancement of the mandrels, and cutting at the connection point white the cutting head and the successive mandrels are advancing.
