Abstract
An apparatus for sealing films together along a path includes a sealing shoe and a counter shoe defining a clearance through which the films pass. The sealing shoe includes an elongated optical energy source having a length dimension oriented generally parallel to the sealing path; a reflector for focussing light emitted by the energy source; a window transparent to the light and having an outer surface adapted to be oriented toward the counter shoe for sealing the films by the light; and a firing arrangement for activating the energy source. The window and the counter shoe are urged toward one another.
