Apparatus for splicing films or the like
Abstract
Abstract A PORTABLE FILM SPLICING APPARATUS WHEREIN TWO FILM SUPPORTING PLATFORMS CAN TURN ON A SHAFT AND ARE BIASED AXIALLY TOWARD EACH OTHER TO NORMALLY BEAR AGAINST THE OPPOSITE ENDS OF A DISTANCING SLEEVE ON THE SHAFT. ONE OF THE PLATFORMS IS PIVOTABLE ON THE SHAFT BETWEEN A FIRST POSITION IN WHICH THE FILM PORTIONS ON THE TWO PLATFORMS ARE PARALLEL TO AND COPLANAR WITH EACH OTHER AND A SECOND POSITION IN WHICH THE FILM PORTIONS OVERLIE AND BEAR AGAINST EACH OTHER. TWO KNIVES CAN BE PIVOTED INTO ENGAGEMENT WITH COUNTERKNIVES ON THE PLATFORMS IN THE FIRST POSITION OF THE ONE PLATFORM TO TRIM THE CORRESPONDING FILM PORTIONS AND TO SIMULTANEOUSLY MOVE THE PLATFORMS AWAY FROM THE DISTANCING SLEEVE. SUCH KNIVES ARE ADJACENT TO TWO SCRAPING MEMBERS WHICH CAN BE RECIPROCATED BY HAND TO ROUGHEN THE FILM PORTIONS ADJACENT TO THEIR TRIMMED ENDS. THE THUS ROUGHENED FILM PORTIONS ARE COATED WITH ADHESIVE AFTER THE KNIVES ARE MOVED AWAY FROM THE PLATFORMS SO THAT THE ONE PLATFORM CAN BE PIVOTED TO SECOND POSITION IN WHICH THE ADHESIVE-COATED FILM PORTIONS ARE CEMENTED TO EACH OTHER TO FORM A LAP SPLICE.
