Abstract: An apparatus is disclosed for splicing a web of paper, which is being paid out from a one web roll and fed into a printing press, to another web roll being rotated in a splicing position in which this new web roll of any diameter is spaced a prescribed unvarying distance from the old web traveling along a predefined path into the press. Since the peripheral speed of the new web roll must be equal to the running speed of the old web before splicing, a sensor positioning mechanism is provided for adjustably moving a photoelectric web roll speed sensor along two orthogonal axes to an optimum sensing position with respect to the new web roll, no matter how large it may be in diameter.

Abstract: A roll splicing system and method is used to splice a new roll to an expiring roll of material. Each roll includes an adhesive region disposed proximate a trailing end of the strip of material rolled around a core region of the roll. As an expiring roll expires or unrolls, the adhesive region is exposed and adheres to an adhesive adherable region on the leading end of a new roll that is rotating against the expiring roll in an opposing direction. The leading end of the new roll is thereby effectively spliced to the trailing end of the expiring roll. A trailing non-adherable region is disposed opposite the adhesive region so that the trailing non-adherable region contacts the adhesive region when rolled and prevents the strip of material from sticking to the adhesive region. The roll splicing system and method can be used to splice strips of material having adherable surfaces on both sides or having a non-adherable surface, such as a silicone coating, on one side of the strip of material.

The second roll, depleted because the labels are applied to articles in an assembly line, has photosensitive device that registers this depletion as the second roll is consumed. The device initiates splicing the leading label to a label in the depleted roll. A controller also responds to the device by moving the dancer arm to a predetermined position in order to control the registration of the leading label with the last labels in the second roll. The controller also responds to a count of the labels that are in the web between the production line and the splice in order to identify the article to which the splice has been applied to eject that article from the production line.
