Patent number: 6911101Abstract: From a supply reel which is set in position at an ACF (Anisotropic Concuctive Film) feeding station, an ACF tape having an ACF laminated on one side of a liner tape is drawn out by an ACF bonding means. At least two reel mount members are provided on a reel stand at the ACF feeding station to mount two ACF tape supply reels concurrently thereon. The reel stand is connected to a switch means thereby to switch the two reel mount members either to an operating or tape supplying position or a standby position. As soon as an ACF tape from a supply reel in the operating position is consumed completely, a fresh supply reel in the standby position is switched into the operating position to continue the supply of the ACF tape.Type: GrantFiled: July 7, 2003Date of Patent: June 28, 2005Assignee: Hitachi High-Tech Electronics Engineering Co., Ltd.Inventors: Jun Onoshiro, Kenya Wada, Ichiyo Ando

Patent number: 6887329Abstract: A supply of sheet stock material for use in a cushioning conversion machine is disclosed. The supply of stock material includes at least one ply of sheet stock material rolled or folded into a compact configuration such as a roll of wound stock material or a stack of fan-folded stock material. The ply has disposed on a leading or trailing end thereof, a pressure sensitive adhesive layer and a removable release liner covering the pressure sensitive adhesive layer. When a supply of sheet stock material is almost spent, a succeeding supply of stock material may be spliced to the almost spent supply by removing the release liner to expose the adhesive and then applying the leading or trailing end, having the adhesive thereon, to a trailing end of the almost spent supply of stock material or leading end of the succeeding supply of stock material.Type: GrantFiled: June 29, 2004Date of Patent: May 3, 2005Assignee: Ranpak Corp.Inventor: Joseph J.

Patent number: 6887328Abstract: A method is described for splicing together overlapping ends of first and second lengths of photographic film strips of common film strip width, comprising positioning a bonding element between an overlapping end of the first length of photographic film and a corresponding overlapped end of the second length of photographic film, and heating the bonding element to effect an adhesive bond between such film ends, wherein the bonding element comprises an induction heating receptive support and thermoplastic adhesive layers on each side of the support, and wherein the heating of the bonding element is performed by induction heating. The present invention allows for the preparation of photographic film splices, consisting of either homogeneous or dissimilar film bases, using a bonding element and induction heating to provide smooth yet strong splices. In particular, the invention enables successful splicing of acetate support (e.g., cellulose triacetate (CTA)) based films and polyester support (e.g.Type: GrantFiled: November 18, 2003Date of Patent: May 3, 2005Assignee: Eastman Kodak CompanyInventors: Thomas M.
