An apparatus invention relates to an apparatus for pulling transverse fins onto a plurality of pipes which are arranged fixed in position alongside of each other by means of carriers the ends of which are operatively supported on respective endless carrier-conveyor chains between a working position engaging the fin plates and a disengagement position releasing the fin plates, the carrier being provided with at least one support foot which holds the carrier in the working position. The support foot is supported on support members of a control device which holds the carriers in the working position on the transport path until release of the transverse fins and releases them for swinging depending on the fin spacing and the transverse fins which have already been pulled-on, the point of release moving in a direction opposite the direction of movement of the carrier conveyor chains. In order to reduce the friction and increase the reliability of operation, the fin pull-on path is divided into a transport region and a control region. Furthermore the control device comprises a control side which is arranged at the end of the transport path and on which the carriers support themselves by at least one support foot. |
