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. For controlling the speed of an unwinding roll two driving belt units are provided which can cooperate with the periphery of the unwinding roll one after another. For running a new roll up to the required peripheral speed for making a splice with an unwinding web and keeping said roll at that speed until the splice is made a core drive is provided which acts upon the shaft of the new roll, and which can work independently of the driving belt units. A new roll can thus be prepared with an adhesive strip over the whole width of the roll, which will result in an uninterrupted splice. The device is further provided with a new web splicing unit.
