A control mechanism for tambour-type door closures helically wound about a winding sleeve for use in combination with cabinetry and including a worm/pinion gear combination releasably locked against free rotation, with controlled rotation of the worm facilitating adjustment of spring tension for controlled ongoing smooth operation of the tambour door closure between open and closed dispositions. The worm/pinion gear combination is coupled to a coiled spring which is helically wound about the tambour door winding spindle with one end of the coil spring being anchored to the rotatable winding spindle means, and with the other being coupled to and fixed for controlled rotational movement with the pinion component of the worm/pinion gear combination. Controlled rotatable motion of the worm is facilitated through the clutching action of the knurled end terminal of the worm gear shaft. The closed position of the tambour door is held against the stored tension of the coil spring by means of a resilient detent member projecting into the lateral guide track for engagement with components of the door panel components.
