Abstract
Method of preparing for a splice, characterized in that a reel (1) is rotatably mounted in a reel holder (2) and a pressure roll (3) is pressed against the reel (1), underneath or at the side of the reel holder (2) and parallel to the axis (4) of the reel (1), by means of a pressure system (5), and separates the upper layers of the reel (1) with a transverse cut (A), whereupon the cut ends (6-10) of the web slip off the circumference of the reel (1) to the left and right as a result of gravity or as a result of slight assistance, so that they now hang down to the right and left of the pressure roll (3).
Claims6
Method of preparing for a splice, characterized in that
- a) a reel (1) is rotatably mounted in a reel holder (2) and a pressure roll (3) is pressed against the reel (1), underneath or at the side of the reel holder (2) and parallel to the axis (4) of the reel (1), by means of a pressure system (5), and separates the upper layers of the reel (1) with a transverse cut (A), whereupon the cut ends (6-10) of the web slip off the circumference of the reel (1) to the left and right as a result of gravity or as a result of slight assistance, so that they now hang down to the right and left of the pressure roll (3),
- b) whereupon a double-sided adhesive splicing tape (12) is stuck transversely to the upper, uncut or undamaged web (11) of the reel (1), and from the divided release paper or release film (13) which is located on the rear of the said tape, that part (14) which is arranged at the end of the reel (1) and can be covered by the hanging end (6) of the web on the reel (1) is pulled off,
- c) then, as a result of rotation (8) of the reel (1) counter to the running direction of its web, the hanging end (6) of the web, as the last layer which has slipped off, is fixed to the adhesive splicing tape (12) under the web tension maintained by the pressure roll (3),
- d) whereupon the end (6) of the web that is fixed by the adhesive splicing tape (12) is severed exactly at the edge (C) of the second part (15) of the release paper or the release film (13), which is still present.
