Cutter for end part of intermediate film sandwiched between plate glass

Abstract

Abstract PURPOSE:To provide a titled device which can cut exactly a soft intermediate film, by applying a force in a specified direction to the swelled out part of the intermediate film by means of a rotary brush roll, suppressing the movement of the swelled out part with a guide plate and cutting said part with an endless beltlike cutting blade. CONSTITUTION:Laminated safety glass G produced by interposing an intermediate film B between two sheets of plate glass A formed to a desired size and shape and subjecting the same to a press sticking treatment is mounted to a holder. An endless beltlike blade 9 and a brush roll 11 are rotated and a movable arm 1 is moved to a prescribed position. When the roll 1 moves to the neighborhood of the glass A, it comes into contact with the end part B' of the intermediate film projecting from the circumferential edge of the glass A, presses the part B' to a guide plate 12 and pulls the same outward. The edge of the blade 9 in this stage is made to incise the end part B in the state of intersecting diagonally with the end face of the glass A and the blade is moved in the direction where the angle of diagonal intersection decreases gradually to incise the end part of the film until the side part of the blade 9 having no blade comes into contact with the end face of the glass A, when the arm 1 is moved on the set locus, whereby the end part B' projecting from the circumferential edge of the glass A is cut.
