Abstract (en)
[origin: US6726614B1] A method and device for trimming flaps formed upon joining a leading end of a new roll to the trading end of a web of a preceding roll in which the web, after joining, is guided around an upstream roller, along a straight path and then onto a downstream roller. A nozzle directs an air stream in the direction of movement of the web or along the width thereof to cause the flap to erect. Downstream of the nozzle a blade trims the flap while it is erected by the air stream.
