ABSTRACT:
Individual segments of splicing tape are prepared at a splice cutting station from a continuous length of foil-thin, self adhering splicing tape. Each thusly prepared splicing-tape segment is transported by a vacuum pickup over to a splicing station at which a spool of magnetic tape has been positioned with the ends of the magnetic tape temporarily held in abutting relation by a vacuum operated, tape hold-down assembly. The vacuum pickup now moves to deposit the segment of splicing tape onto the abutting ends of the magnetic tape, and thereafter releases the vacuum hold on the splicing segment and returns to the splice cutting station to repeat the foregoing sequence. Each time the vacuum pickup moves to pickup a new splicing segment it actuates a cutting blade arranged to make a crosswise cut in the continuous length of the splicing tape that is fed around the circumference of a motor driven cutting wheel, the circumference of which forms a cutting surface carefully selected to enable the blade to reliably sever the foil-thin splicing tape. The individual splicing segments are thus formed by successive crosswise cuts spaced at increments along the length of the splicing tape, with such spacing being determined by controlled, incremental rotation of the cutting wheel during the time that the vacuum pickup is moving to and returning from the splicing station.
