Patent ID: 8474129

Claim:
A method for producing lamination packs of a controlled height, the method comprising the steps of: supplying raw material to a press having associated therewith a glue application device, wherein the glue application device is comprised of several glue application units each having a control system, wherein the glue application units each comprise a valve and an actuator, connected to the valve and controlled by the control system; applying glue partially onto an upper surface; a lower surface; or an upper surface and a lower surface of the raw material without the raw material being contacted by the glue application device that applies the glue, wherein the glue is applied by the several glue application units in the form of several glue dots, with each one of application units producing one of the glue dots; supplying to the control systems a control signal for each stroke of the press; varying the number of the glue dots per lamination for varying a lamination pack strength; immediately after applying the glue, punching laminations from the raw material with a tool of the press such that the tool does not contact the glue dots applied to the raw material; assembling several of the laminations to a lamination pack.
