Butler Automatic, Middleborough, Mass., developed an enhanced register sensor for new and existing SP1 Automatic Film Splicers.

The new register sensor uses registration marks on the film to provide an automatic, in-registration butt splice. In doing so, the splicer provides the downstream process with a consistent product pitch or imprint spacing, eliminating the need for re-registering the film in the process after a splice.

Also, manufacturers are now able to print across the full width of the film, even when the print is similar in color to the black register marks.
While the prior design required the operator to physically relocate the sensor in the in-web direction when adjusting between products of different length or pitch, the new control software allows the operator to achieve the same result simply by entering an offset value on the touch screen user interface. This enhancement allows operators to more easily locate the splice in different positions on the final product.
