ABSTRACT:
A device for splicing the trailing (downstream) end of a first web of material (the expiring web) originating from a first roll to a leading (upstream) end of a second web of material (the new web) originating from a second roll, during stoppage, comprises a frame which accommodates at least a festoon, a web splicing unit and two roll holders. Each roll holder comprises two arms which are fitted so as to be slideable in the axial direction and non-rotatable on a pivot shaft mounted horizontally in the frame and coupled to a rotating mechanism.
Each roll holder further comprises two chucks rotatably mounted in the ends of the arms and situated opposite each other coaxially for receiving a roll between them. A vertically arranged drive belt unit is situated between the arms of each roll holder for rotationally driving a roll received between the two chucks. With the roll holder a roll can be easily picked up and pressed against a drive belt.
