ABSTRACT:
Processes and apparatus for fabricating belts are disclosed comprising conveying a first mandrel to a wrapping station, supplying the leading edge of a web from a web supply roll to the first mandrel at the wrapping station, retaining the leading edge of the web on the first mandrel by means of a partial vacuum, wrapping the web around the first mandrel by rotating the first mandrel for about one revolution, severing the web at the wrapping station to form a trailing edge which overlaps the leading edge of the web to form a first belt having a seam, substantially simultaneously conveying the first mandrel to a welding station and conveying a second mandrel to the wrapping station, and substantially simultaneously wrapping the second mandrel with fresh web material from the web supply roll and welding the seam on the first belt on the first mandrel to form a unitary belt. These welded belts may be automatically removed from the mandrels at a belt discharge station.
