Abstract: A heated windshield wiper assembly which employs heated forced air generated by a heater-blower powered by a cigarette lighter accessory that flows therefrom through conduits attached to each wiper arm that, in turn, are attached to inlet ports on the blade housing disposed at the outer end of the wiper arms. Each blade housing has an air chamber, fluidly connected to the inlet port, with a pocket on each side of the wiper blade therein to keep both the blade housing and wiper blade warm and a plurality of outlets on a bottom side of the blade housing through which the heated air flow generated by the heater-blower also exits onto the wiper blade and onto the windshield.

Abstract: A method for reducing or eliminating forming fabric edge curl includes slitting or scoring the knuckles formed by cross-machine direction yarns on the long-shute knuckle side of a papermaker's forming fabric. The knuckles are scored or slit to a depth no greater than half the diameter of the cross-machine direction yarns. At least one such slit or score is provided per knuckle. The scoring or slitting has the effect of bringing the ratio between the shrink forces acting on the two sides of the forming fabric in the cross-machine direction closer to unity, and, in turn, reduces or eliminates the edge curl resulting from shrinkage in the cross-machine direction.
