MATERIAL SUPPLY APPARATUS FOR SECONDARY BATTERY SEPARATOR

The present invention provides a raw material supply device for a separator of a secondary battery comprising a conveying unit for causing the end portion of the supplied raw material to move to the end portion of the existing raw material; and a bonding unit for bonding the end portion of the supplied raw material and the end portion of the existing raw material. The raw material supply device may automatically bond the existing raw material and the supplied raw material by using ultrasonic waves with respect to the raw material for the separator of the secondary battery in the form of a roll.
