  • Patent number: 3953275
    Abstract: A method and apparatus for applying liquid adhesive to the outer surface of a stack of laminations are provided which results in more precise adhesive application. The laminations are placed on a mandrel which is mounted for reciprocal movement along the longitudinal axis of the mandrel. The adhesive is applied by roller pads which abut the laminations during mandrel movement. The direction and speed of roller pad rotation is coordinated with the mandrel speed and the direction of mandrel movement. This coordinated movement prevents lamination fanning and adhesive smear during application of the adhesive to the lamination stack. Means are provided for adjusting the rate at which adhesive is supplied to the roller pads from an associated adhesive reservoir and for adjusting the pressure with which the roller pads abut the lamination stack.
