ABSTRACT:
Apparatus for splicing a running web to the leader of a fresh web by means of a uniting band both sides of which are coated with adhesive has a holding device which is placed between the running web and the leader of the fresh web while such leader adheres to suction ports of one of two stationary positioning devices. Two hammers are mounted at the opposite sides of the path for the running web and are movable toward each other to press the running web and the leader of the fresh web against opposite sides of the uniting band in the holding device. The hammers carry mobile cutters which cooperate with complementary cutters, and mobile knives which can cooperate with a fixed knife on the holding device. The arrangement is such that, when a pneumatic motor causes the hammers to move toward each other, the mobile cutter for the fresh web cooperates with the respective complementary cutter to trim the leader of the fresh web ahead of the holding device and th mobile knife for the running web cooperates with the fixed knife to sever the running web behind the uniting band. The holding device is thereupon reoriented and a new uniting band is attached thereto to thus prepare the apparatus for the next splicing operation. The remnant of the roll of running web is replaced with a roll of fresh web and the leader of such web is threaded through the apparatus and attached to the corresponding positioning device. The diameters of rolls can be monitored to automatically arrest the advancing rolls for the running web and to start the pneumatic motor when the supply of running web is depleted.
