ABSTRACT:
Method and apparatus for processing solar panel elements which have been cut from relatively long lengths of metal tubing secured to metal strip and which are to be joined at their opposite ends to headers. At a first station, the elements are, if necessary, stretched in the longitudinal direction and straightened, and the tube end portions are shaped so as to be substantially circular in cross-section. At a second station, the exterior surfaces of the tube end portions are machined to the desired diameter, and portions of the strip immediately adjacent to the tube end portions are removed. At a third station, the remaining portions of the strip outwardly of the previously removed portions thereof are removed by shearing. The elements are moved step-wise from station to station, and three panel elements may be processed simultaneously.
