ABSTRACT:
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 two ends of which are swingably supported on respective endless carrier conveyor chains between a work position engaging the fin plates and a disengagement position releasing the fin plates, the carriers being provided with a support foot which holds the carriers in the work position. The support foot is supported on support members of an endless control chain which extend over the respective length of the pull-on region for the transverse fins and are moved by the control chain opposite the direction of movement of the carrier conveyor chains for the displacement of the point of release of the carriers corresponding to the transverse fins which have already been pulled on. In order to reduce the friction and increase the reliability of operation, at least one control chain is constructed as a three-strand chain the outer strands of which are supported on stationary support rails while its central strand is a direct support for the support feet of the carriers solely in the pull-on region.
