Apparatus for joining plastic tubes

An apparatus for joining an end section of a first roll of plastic tubes to a start section of a second roll of plastic tubes, comprising a surface on which an end section of a first plastic tube is deposited, and comprising a fixing surface for temporarily fixing to the apparatus a region of the end section of the first plastic tube, wherein a movable treatment body for treating the end section of the first plastic tube is provided above the depositing surface wherein the treatment body is movable relative to the depositing surface both in a longitudinal direction (L) along which the plastic tubes are transported during operation and in a direction (R) perpendicular to the depositing surface, wherein the treatment body comprises at least one roller which is pivotable about a rotation axis (X) which is perpendicular to a plane defined by the directions (R) and (L) and wherein the roller is arranged to roll over joining end section in order to consolidate the join, wherein the apparatus further comprises a holding rod which is arranged parallel to the treatment body, and wherein end sections of the holding rod are guided in an angled groove, which also serves as an arresting means for the treatment body, wherein the holding rod which is placed in the groove can nevertheless be fixed in a predefined end position.
