摘要

Method and device for connecting the end (3) of a flattened tube (4) of plastic foil to the beginning (1) of a subsequent tube (2), said tubes (4, 2) being used in particular for applying sleeves onto bottles or like objects. The leading end (5) of the beginning (1) of a flattened tube (2) is provided with an obliquely cut-away corner (7) at both longitudinal edges (6). The thus established two loose lips (8) are separated from each other and the end (3) of the spent tube (4) is slid between the lips and fixed in relation to said lips. The materials of said tubes are melted together by a short-time, pressurized supply of heat.
