Abstract
An apparatus and method for effecting a splice between a pair of feed rolls for successively supplying film material to a film utilization device, such as a labeling machine. Downstream from the rolls, a splicing station includes a pair of parallel, spaced film paths, carrying film from a respective roll. Movable film pads within the splicing station displace film within a selected path past a film cutter to manufacture a trailing end. Continued displacement of the trailing end brings it into adhesive engagement with the leading end of the other film, disposed within the other film path. A braking station downstream from the splicing station holds fast the film extending from the selected path during the splicing operation. Means to effect in registration splicing of film from the two rolls, while allowing continuous operation of the associated film utilization device, is also disclosed.
