ABSTRACT:
A system for fabrication of absorbent articles includes a linear array of frame modules each having an open interior. Panels are mounted to one face of the modules. Article fabrication mechanisms are mounted to project from the panels. Operating means are disposed within the modules and are operatively engaged through the panels with the fabrication mechanisms. An operating and control system is provided for a machine in which disposable absorbent articles are fabricated. Continuously operating mechanisms are driven by electric motors for continuously operating on moving webs and other components of the article. A main drive shaft is rotated for transferring power through direction phasing mechanical power transfer devices to mechanisms which intermittently effect unity operations with respect to an associated moving web. The direction phasing mechanical power transfer devices are controlled relative to a sensed portion of an article component so as to temporarily vary the speed of the unity operation and effect registration of the operation in a preselected relationship with the associated moving web.
