Abstract
A laminated core product producing apparatus wherein a projection is formed on part of a strip of core sheet material and core sheets are punched out of the strip and assembled in a linearly moving stack into the laminated core product by making use of the mutual fitting and crimping of the projections on the core sheets. The dimension of the laminated core product in the direction of the thickness of the core sheets is determined by controlling the intermittent punching out of the projections. A marking mechanism selectively marks a portion of the lateral side edge of a core sheet to be punched out, and at least one proximity sensor provided adjacent the stacked core sheets being assembled into the core product produces a signal corresponding to the distance of a marked core sheet from the head of the stack during movement of the marked core sheet along the stack. A timing signal generated each time a core sheet is punched out and assembled on the stack, a preset target value of the dimension of the core product, and information about the distance of the proximity sensor from the head of the stack, are also supplied to a control device, which calculates the dimension of the assemb…
