ABSTRACT:
A machine for continuously unrolling, permitting simultaneous unrolling of two side-by-side or coaxial bobbins (1), comprises a chassis (2) on which are guided in rotation two plates (3) parallel to each other and connected by shafts (4 and 5) for the support and guidance of lateral bobbin-carrying arms (6) for the support and driving of bobbins (1), and an intermediate bobbin-carrying arm (7) for the simultaneous unrolling of two side-by-side or coaxial bobbins (1). The frame (2) is moreover provided with a device (8) for cutting and interconnecting ending strips and new bobbins. The intermediate bobbin-carrying arm (7) is articulated and retractable into a non-use position and the device (8) for cutting and connecting ending and new strips, comprises a device (12) for individual application of two ending strips, independently of each other, onto two new strips from bobbins that are side-by-side or coaxial, and for application of a single strip of great width to a single new bobbin (1), as well as a device (14) for cutting and connecting two strips individually and independently or a single strip of great width.
