ABSTRACT:
The invention is directed to a method of and machine for loading a scroll of film and take-up spool into a cartridge and assembling and sealing the cartridge. It includes the steps of supplying a web of film and backing paper to a scrolling mechanism and winding the webs into a scroll. A single guide track guides and assists in advancing the webs of film and backing paper to a winding spindle. Severing mechanisms are located along the guide track to cut the webs into the desired lengths. The winding spindle is engaged by the webs for scrolling within a socket on a first transport carrier. When scrolling is complete the spindle is withdrawn and the scroll is retained in the socket. An ultrasonic securing device is used to secure a free end of the scroll to a take-up spool carried in another socket of the carrier. A transfer mechanism then transfers the spool and scroll from the first carrier into the chambers of a waiting cartridge bottom carried on a further transport carrier device which transports the loaded cartridge bottom to a station where the cartridge cover is placed on the bottom portion. An ultrasonic welding mechanism then seals the cover to the bottom completing the cartridge.
