An apparatus to form gasket grooves on windows and doors is provided to form two different types of gasket grooves using a single apparatus, with improved productivity by increasing a forming speed for the gasket grooves using a high frequency motor. According to the present invention, the apparatus comprises: a first high frequency motor having a roller to form a first gasket groove of an embossing shape on a contact surface with a window frame along a longitudinal movement of the window frame; at least one second high frequency motor having a blade to form a second gasket groove on two opposing surfaces of the first gasket groove by expanding a portion of an inner surface; and a control device to control the first and second high frequency motors. The manufacturing efficiency is improved by automatically mounting the width direction gasket by simply pushing the same upon manufacturing the window frame, except for the case of engaging the gasket in a longitudinal direction due to the gasket shape. With a pair of processing means (the high frequency motors) to form the gasket groove on two opposing surfaces of the gasket groove of a predefined embossing shape by expanding a portion of the inner surface, the gasket grooves can be formed even when one of the motors is out of order and the motors can compensate for the faults in the gasket grooves for completion. |
