Abstract
A method of inserting a pair of connecting portions of an insulation sheet into the slots in a stator core is disclosed. The insulation sheet includes a pair of body portions interconnected at their opposite ends by the connecting portions. The top sheet in a stack of insulation sheets is picked up and manipulated to be disposed in a vertical position. The vertically disposed insulation sheet is then gripped at positions slightly spaced inwardly from the opposite end areas of each body portion. After being gripped, the sheet is moved to a position above the stator core. At the position above the core, the intermediate area of each body portion is bowed to assume a 'U' shape whereas the opposite end areas of each body portion are disposed in registry with predetermined slots of the stator core, respectively. Then, the bowed insulation sheet is moved in a direction parallel to the axis of the stator core into the center of the core, and thereby the connecting portions of the sheet are inserted into the appropriate slots.
