Film splicing apparatus

Abstract

Abstract ADAPTED FOR MOVEMENT TOGETHER WITH ONE MEMBER DISPOSED ON EACH SIDE OF THE PLANE OF THE FILM STRIP. THE WIPER MEMBERS ARE ARRANGED TO ENGAGE THE FILM STRIP WITH THE LENGTH OF TAPE DRAWN THEREABOUT AND TO SMOOTHLY PRESS THE TACKY SIDE OF THE TAPE AGAINST BOTH SURFACES OF THE FILM STRIP COMMENCING FROM THE AFOREMENTIONED ONE EDGE AND TRAVELLING PROGRESSIVELY ACROSS THE WIDTH OF THE FILM ENDS. A FILM SPLICER IS PROVIDED WITH MEANS FOR SUPPORTING END PORTIONS OF TWO LENGTHS OF FILM STRIP IN LONGITUDINAL ALIGNMENT AT A SPLICING STATION AND WITH THEIR ENDS ABUTTING. A KNIFE IS DISPOSED TO CUT OFF LENGTHS OF ADHESIVE TAPE OF THE KIND HAVING A TACKY SIDE AND A NON-TACKY SIDE DRAWN FROM A TAPE SUPPLY. A TRANSPORT MECHANISM IS ARRANGED TO FEED THE FORWARD END OF A LENGTH OF TAPE FROM THE CUTTING KNIFE ALONG A PATH TRANSVERSE TO THE LONGITUDINAL DIRECTION OF THE FILM STRIP OVER AND PAST A FIRST TAPE SUPPORT SURFAE WITH THE NON-TACKY SIDE TURNED THERETOWARDS, PAST THE SPLICING STATION WITH THE TACKY SIDE OF THE TAPE TURNED TOWARDS THE FILM PORTIONS, ABD ONWARD UNTIL THE FORWARD END OF THE TAPE MAKES CONTACT WITH A SECOND TAPE SUPPORT SURFACE BEYOND THE SPLICING STATION AND THE LENGTH OF TAPE SPANS A GAP DEFINED BETWEEN THE TWO TAPE SUPPORT SURFACES. A PAIR OF TAPE ENGAGING ARMS ARE DISPOSED ONE ON EACH SIDE OF THE PLANE OF THE FILM STRIP AT THE SPLICING STATION. THE ARMS ARE MOVABLE TOGETHER GENERALLY TOWARDS THE RESPECTIVE TAPE SUPPORT SURFACES TO ENGAGE THE TACKY SIDE OF THE LENGTH OF TAPE WHEN SPANNED ACROSS THE GAP BETWEEN THE TAPE SUPPORT SURFACES AND ARE MOVABLE TOGETHER AWAY FROM SAID TAPE SUPPORT SURFACES. THE ENDS OF THE TAPE ENGAGING ARMS ARE ARRANGED TO PERFORM A CONTINUOUS CLOSING MOTION TOWARDS EACH OTHER DURING THE RETURN MOVEMENT FROM THE TAPE SUPPORT SURFACES AND IN SUCH MANNER AS TO DRAW THE LENGTH OF TAPE ADHERING TO THE ENDS OF THE ARMS ABOUT THE ABUTTING END PORTIONS OF THE FILM STRIP COMMENCING FROM ONE EDGE THEREOF. WIPER MEANS ARE ALSO PROVIDE, COMPRISING A PAIR OF WIPER MEMBERS BIASED TOWARDS EACH OTHER AND
