The invention relates to a blade for an indoor bandy stick, comprising a top-edge reinforcing rib (5), a bottom-edge reinforcing rib (6) and therebetween a number of reinforcing ribs (7, 9) which lie lengthwise of the blade and are spaced from each other so as to form open spaces between the lengthwise ribs (5, 6, 7, 9). The interspace between the mid-section reinforcing ribs (7) is located at the distance of a radius (D/2) of a ball (3) from the bottom edge of a blade (12). Thus, the ball hits the reinforcing ribs at more than one point along the ball surface. One or both sides of the blade can be concave.

A method for impregnating fibre bundles with molten or liquid resin in manufacturing a fibre-reinforced material, which material comprises one or more fibre bundles, wherein each fibre is surrounded by matrix resin, by impregnating a continuous web (10;10a) of one or more fibre bundles with molten or liquid resin (32, 33) and solidifying the resin by cooling or chemical reaction. During the impregnation the molten or liquid resin (35) material is made subject to shear forces by bringing it between two closely nearby surfaces (10;10a, 36;37) which are in moving relationship to each other.

Method and apparatus for manufacturing fibre-reinforcing material

A method is disclosed for impregnating fibre bundles with molten or liquid resin (24, 29) in manufacturing a fibre-reinforced material, which material comprises fibre bundle or bundled groups of fibres, wherein each fibre is surrounded by matrix resin, by impregnating a continuous web (10, 10a) of one or more fibre bundles with molten or liquid resin (24, 29) and solidifying said resin by cooling or chemical reaction. Before said impregnation the molten or liquid resin material (29) is made subject to shear forces by bringing it to flow between two closely nearby surfaces (26, 27) which are in moving relationship into each other.
