Abstract
A method for unwinding includes loading a first reel of web material into a first unwind position where the web is unwound. A splicing unit is then moved in the machine direction toward the first unwind position until there is sufficient space to allow a further reel to be loaded into a second unwind position where the web from the second reel is unwound once loaded. Then, the web from the first reel is spliced to the second reel, and the web of the first reel is thereafter cut. The process continues in the opposite direction after removing the first reel from the first unwind position. The web of the second reel is unwound in the second position, the splicing unit is moved toward the second unwind position until there is sufficient space to allow a further reel to be loaded into the first unwind position.
Claims10
A method for unwinding reels in an unwinding system, the method comprising the steps of:
- (i) loading a first reel comprising a convolutely wound web material into a first unwind position,
- (ii) unwinding the web of the first reel in the first unwind position,
- (iii) moving a splicing unit toward the first unwind position until there is sufficient space to allow a further reel to be loaded into a second unwind position,
- (iv) loading a second reel comprising a convolutely wound web into the second unwind position,
- (v) splicing the web from the first reel to the second reel, and
- (vi) cutting the web of the first reel.
