Abstract
The invention relates to a method for the extrusion and labelling of a packaging tube (14), comprising the following successive steps performed on an extrusion-labelling line, namely: a) forming a partially or fully tubular label (17) from a film (12); b) introducing the label (17) into a calibration element (22); c) extruding a tubular body (13) on the side of the concave surface of the label (17); d) bringing the external surface of the tubular body (13) into contact with the concave surface of the label (17), step (c) being performed in the calibration element (22). The invention also relates to an extrusion-labelling device and a packaging tube.
Claims17
A method for extrusion and labelling a packaging tube, performed on an extrusion-labelling line, comprising the steps of:
- forming a partially or fully tubular label from a film;
- continuously feeding the film of the tubular label into a calibration device;
- continuously extruding a tubular body and feeding the tubular body to a side of a concave surface of the tubular label;
- and
- bringing an external surface of the tubular body into contact with the concave surface of the tubular label whilst passing the tubular body and the tubular label through the calibration device,
- wherein the step of extruding is performed inside the calibration device.
