1,240,201. Impregnating rovings. HERCULES Inc. 2 April, 1969 [9 April, 1968], No. 17402/69. Heading D1L. A roving is passed through a resin chamber comprising a plurality of compartments separated by removable partitions each carrying a plurality of guide elements and deformable sealing elements which compress the roving, extracting air trapped between the filaments, and prevent resin from passing with the filaments from one compartment to another. The roving is finally passed out of the chamber through an exit seal. As illustrated, resin passes into the chamber 1 through the inlet 15, falling successive compartments 14, 12 by flowing over the top of the partitions 11. The resin is maintained at a constant temperature by heating fluid flowing in a path defined by baffles between the double walls of the base 2, sides 3 and 4 and inlet end 5. The partitions 11 which decrease in height from the filament extend to the filament input end are vertically slidably removable and have end pieces 19 separated by three guide elements 18 and three inflatable sealing elements 21, alternately disposed, and a wall 20. A roving R, guided by rods 29, 30 and 31, passes through the resin compartments in a zig-zag path, being compressed between a guide element and sealing element of each successive partition, and finally passes through an outlet seal 36, comprising an inner member 46 and a disc 45 which seal the chamber against resin leakage while allowing the passage of a roving therethrough. The partitions may be vertically pivotally removable (see Figs. 5-7) in Which case the guide elements and sealing elements are horizontally disposed. |
