Abstract
A fiber reinforced construction and method for a loom shuttle is disclosed which includes a plurality of layers 26, 28, 30 of a reinforcing fabric F laminated with conventional layers 18 across a section of the yarn eye slot E formed in the shed side wall 12 of the shuttle. The reinforcing fabric F includes reinforcing fibers, preferably Kevlar, woven in the filling direction which are oriented along the height of the side wall reinforcing the yarn eye section. The side wall is effectively reinforced against splitting caused by forces imparted by the actions of the picker stick and shuttle box on the loom.

A loom shuttle of the type having first and second side walls constructed from conventional laminated layers of resin impregnated fabric a yarn eye slot formed in a first side wall of said shuttle through which yarn is guided and withdrawn during weaving wherein the improvement comprises:
- a plurality of additional reinforcing layers of reinforcing fabric laminated with said conventional laminated layers of conventional fabric;
- said additional reinforcing layers being included and oriented only in said first side wall laminated with said conventional laminated layers;
- said second side wall including only said conventional laminated layers of resin impregnated fabric;
- said additional reinforcing layers of reinforcing fabric including synthetic reinforcing fibers extending height wise in the direction of height of said first side wall having a strength greater than the corresponding fibers of said conventional layers;
- and
- said additional reinforcing layers being oriented across a section of said yarn eye slot in said first side wall with said height wise extending synthetic reinforcing fibers reinforcing the tensile strength of said first wall in the height direction of said side wall;
- whereby splitting of said first side wall in the area of said eye slot is reduced.
A method of reinforcing an eye slot section in a laminated shuttle of the type which includes first and second side walls having first laminated layers of resin impregnated fabric wherein an eye slot is formed in the first side wall of said shuttle, said method comprising:
- including in said first side wall of said shuttle a plurality of additional layers of reinforcing fabric laminated in a section extending through said eye slot wherein the fabric includes synthetic reinforcing fibers;
- and
- including said additional layers of reinforcing fabric in said first side wall in addition to said first laminated layers of fabric in said first and second side walls so that said layers additional of reinforcing fabric laminated in said eye slot section are not included in said second side wall.
