Apparatus for splicing webs of cigarette paper
Abstract
Abstract THE LEADING END OF A FRESH WEB WHICH IS STORED ON A REEL IS AUTOMATICALLY SPLICED TO AN EXPIRING WEB WHEN THE MACHINE WHICH CONSUMES THE EXPIRING WEB AND DRAWS SUCH EXPIRING WEB FROM A SOURCE OF SUPPLY IS ARRESTED IN RESPONSE TO A SIGNAL FROM A DETECTOR WHICH SCANS THE SUPPLY OF EXPIRING WEB AND PRODUCES THE SIGNAL WHEN THE SUPPLY OF EXPIRING WEB IS DEPLETED TO A PREDETERMINED MINIMUM VALUE. THE CONSUMING MACHINE IS STARTED WITH A PREDETERMINED DELAY FOLLOWING COMPLETION OF THE SPLICING OPERATION AND IS ACCELERATED TO NORMAL OPERATING SPEED IN SEVERAL STAGES AT SUCH A RATE THAT THE UNITED WEBS WHICH ARE ACCELERATED IN RESPONSE TO ACCELERATION OF THE CONSUMING MACHINE ARE NOT SUBJECTED TO EXCESSIVE TENSILE STRESSES.
