This invention pertains to processing continuous webs such as paper, film, composites,
and the like, in dynamic continuous processing operations. More particularly, it
relates to transferring discrete parts to a continuous web, whether paper, film,
composite, or the like. Specifically, the invention relates to methods and apparatus
for taking discrete parts from a source in a taking zone, optionally taking the
discrete parts as components of a continuous web, onto a transport head on a transfer
assembly, severing the discrete parts from the continuous web if received as part
of a continuous web, rotating the transfer assembly about a first axis and correspondingly
rotating the transport head about a second axis radial to the first axis, to thereby
present the discrete parts to a receiver in a transfer zone, and transferring the
discrete parts to the receiver in the transfer zone. The invention includes using
a roughened taking section on the transport head, interacting with textured surface
on the discrete parts, to hold the discrete parts to the transport head, with optional
use of suction through the transport head to assist in holding the discrete parts
to the transport head. Novel apparatus is included for delivering suction to and
through rotating slip rings.
