ABSTRACT:
A method for manufacturing a magnetotherapeutic back massager. A roller blank having a central cylindrical core circumscribed by a pair of spaced apart circular projections receives magnets in the circular projections to provide magnetic properties to the resultingly constructed magnetotherapeutic back massager. Preferably, the magnets are arranged so as to alternate polarity and a magnet-supporting strip holds the magnets together prior to and during the association of the magnets with the circular projections. The circular projections may have indentations or grooves to accommodate the magnets. Once the magnets have been associated with the circular projections, the magnets are more permanently attached by applying additional material to the circular projections so as to seal the magnets to the circular projections. The sealing material may be the same as that used to construct the roller blank, preferably latex rubber. Either prior to or after the sealing process, the magnet-supporting strip is removed from the magnets leaving them held in place by the circular projections of the roller blank. A cover, preferably bi-lobed and knobbed, is then applied to the now-magnetized roller blank. Roller bearings attached to the roller blank allow the central, bi-lobed massaging core to articulate rotatably with respect to the central spindle shaft. The central spindle shaft may have handles at opposite ends to facilitate manipulation of the resultingly-constructed magnetotherapeutic back massager.
