Abstract: The present invention is comprised of a fixed line for flexible line rotary trimmers in which one or more relatively short fixed lengths of cutting line are inserted into the original manufacturers equipment opposed orifices placed in the outer side wall of the trimmer line head housing and are secured in place by means of an encapsulated metal grommet The best use of current invention is to insert one end of fixed line into trimmer heads original equipment orifices and pull line until it is secured to the trimmer head by the grommet and rubberized encapsulation material. After use the worn or broken fixed trimmer line can be simply removed by grasping the encapsulated metal grommet and pulling the line from the trimmer head and new line can be reinstalled simply by repeating above installation steps.

Abstract: A manifold for a hot process injection molding apparatus includes a two piece manifold assembly. A first manifold section which includes a longitudinal melt channel and a nozzle drop to a mold is fixably secured to a manifold cavity of the apparatus. A second manifold section also including a longitudinal melt channel is sealably and slidably coupled with the first manifold section for fluidly communicating molding material from the second melt channel to the first melt channel. Expansion and contraction of the manifold sections are taken up by the slidable coupling.
