Japanese Patent JPS6251071

B2

A lamination bundle or stack for a long-statorlinear motor. Each lamination is made of a thin, siliconized metal sheet for the electrical industry with a thickness of between 0.35 to 1.00 mm, and at one end of its narrow side has a recess, and at its opposite end has an extension corresponding to this recess for a positive or form-locking arrangement of the bundles in rows adjacent to each other. Of the teeth laterally defining the grooves for cable windings each end tooth has a width which corresponds to half the width of the adjacent tooth and at its free end is cut at an incline, whereby the inclined cutting line extends from the groove to the end of the narrow side. The laminations are stacked so as to completely cover each other, and have their contacting surfaces glued together over the entire surface area thereof. According to the method of producing the laminated bundle, a thin strip of sheet metal for the electrical industry, coated on both sides with a duroplastic adhesive and unwound from a drum, is fed by a feeding or advancing device to a punch; thereupon, these laminations are punched out from the metal sheet, are subsequently stacked upon each other in a magazine, and are adhesively joined with each other into a bundle or packet; thereafter, the laminated bundle of laminations is first conveyed through different thermal treatment zones arranged one after the other, and is subsequently supplied to a device for coating the bundle of laminations with a corrosion protective layer.
