Abstract: A web splicing method and apparatus to splice a running web to the web on a ready roll so as to avoid web speed and position mis-matches due to roll eccentricity and roll end wobble. After an adhesive splicing medium is applied to the leading end of the web on the ready roll, that roll is accelerated to a selected nominal splicing speed. The roll surface speed and end edge position are then measured at least at a location at or near the splicing medium thereon. The speed and edge position of the running web are also measured. During successive revolutions of the roll, the running web speed and the roll surface speed in the vicinity of the splicing medium are compared to produce speed difference signals which are applied to control the speed of the running web and/or the roll to match the speed of the running web and the surface speed of the roll at or near the splicing medium.

Excess adhesive which is not covered by substrate from a new roll is deactivated by a deactivating element (7) positioned in advance of any deflection roller to prevent accumulation of adhesive on any elements of the roll changer of the printing machine.

Abstract: In a device for continuously feeding a web of material from a stock roll, a conveyor means for conveying the unwinding roll and the remnant roll through the device comprise two parallel essentially U-shaped guide tracks for the rolls. The legs of the U extend in lengthwise direction of the device, such that both loading of a new roll and picking up and discharging of a remnant roll can take place at the front side of the device.
