Abstract:
1. A method of continuously feeding ACF tapes one after another from supply reels set in a feed position and a standby position on a reel stand, continuing ACF tape feed by automatically switching a fresh supply reel from said standby position to said feed position as soon as an ACF tape on a supply reel in said feed position has been consumed to a tape end, said method comprising the steps of: withdrawing an ACF tape, with an ACF laminated on a liner tape, from a supply reel in said feed position on said reel stand by the use of a drawing chuck member, and bonding said ACF repeatedly on a substrate by the use of a bonding roller while peeling off said liner tape from said ACF by the use of a peeling roller; setting a fresh supply reel in said standby position at an arbitrary time point during an ACF bonding operation and letting a tape end holder member grip by suction force a leading end portion of an ACF tape from said fresh reel; as soon as said supply reel in said feed position is consumed to a tape end, turning said reel stand to switch reel positions from said feed position to standby position or vice verse, bringing said fresh supply reel to said feed position; and handing said leading end portion of said ACF tape on said tape end holder member over to said drawing chuck member, routing said ACF tape under said bonding roller and over said peeling roller.
