Abstract
A method and apparatus for forming flanges of fiberglass reinforced plastic on a tubular member, the method including the steps of soaking at least one fiberglass strand which is directed to a rotating tubular member whereinafter such strand is wound and laterally distributed about the tubular member forming a plurality of layers with such layers being constrained to form an annular flange on the tubular member of a predetermined axial cross sectional width and height.
Claims7
A method for forming flanges of fiberglass reinforced plastic on a tubular member, comprising the steps of:
- soaking at least one fiberglass strand with a resin;
- mounting the tubular member with a face plate;
- rotating the face plate having the tubular member therewith;
- directing the resin soaked fiberglass strand to the rotating tubular member;
- winding the resin soaked fiberglass strand on the tubular member while the tubular member is rotated to form a plurality of layers;
- laterally distributing the resin soaked fiberglass strand on the tubular member between the face plate and an adjustable guide member assembly mounted with the face plate and disposed about the tubular member for forming an annular flange of a predetermined axial cross-sectional width;
- and
- compacting the fiberglass strand on the tubular member by moving a distribution header laterally of the tubular member for providing substantially uniform compacting of the strands and substantially uniform axial cross-sectional height of the flange.
An apparatus for forming an annular flange of fiberglass reinforced plastic on a tubular member, comprising:
- means for soaking at least one fiberglass strand with a resin;
- a face plate for mounting the tubular member therewith;
- means for rotating said face plate having the tubular member therewith;
- a guide member adapted to be positioned about the tubular member and mounted with said face plate;
- distribution means with said rotating means for distributing said resin soaked fiberglass strand between said face plate and said guide member on the tubular member, said distribution means permitting winding and lateral distribution of said resin soaked fiberglass strand on the tubular member while the tubular member is rotated by said rotating means to form an annular flange of a plurality of layers having a predetermined axial cross-sectional width;
- and
- compacting means for compacting said layers of resin soaked fiberglass strands to prevent undesired voids being formed in said plural layers as well as to promote uniform packing density of said fiberglass strand for the annular flange, said compacting means being integral with said distribution means.
