Abstract
Abstract Web supply apparatus for supplying relatively stiff web material such as liner board for a corrugator serves the web from one of two supply rolls. The running web passes through a splicing station and a festoon on its way to the web-consuming machine. The leading end of the ready web is prepared on a web positioning bar away from the splicing station and then carried by the bar to the splicing station while the running web is being consumed. When the roll of running web expires, a control system automatically stops the roll of running web and special pressure pads at the splicing station press the running web and ready web together to make a strong splice between them. Immediately thereafter, a knive fires directly behind the splice, thereby cutting the trailing end of the running web. The pressure pads firmly grip the webs above and below the line of the cut so that the knife slices cleanly through the web. Following this, the roll of ready web is accelerated and the trailing end of the running web pulls the ready web into the festoon which then refills to complete the splicing cycle. When the apparatus incorporates roll stands of the rollout type, the web positioning bars are affixed directly to the roll stands and move in and out of the splicing station with them. When the roll stands are of the fixed type, the positioning bars are moved from a remote loading station to the splicing station by a special transport assembly. Also, the positioning bars can be moved manually from the preparation site to the splicing station if the situation demands it. Thus, the splicing is accomplished at zero speed with maximum reliability, yet the stiff web proceeds uninterruptedly and at constant speed to the corrugator.
