A card wire has consecutive teeth spaced apart in the longitudinal direction by a pitch. The teeth are bounded in the longitudinal direction by a tooth face on a first side and by a tooth back on a second side. Looking downwards in the height direction of the card wire, the tooth face and the tooth back of consecutive teeth merge in a tooth base and, looking upwards in the height direction, form a tooth tip. The tooth depth is defined by the greatest distance, in the height direction of the card wire, from the tooth tip to the tooth base. The ratio of pitch to tooth depth is less than 1.1. An interspace, measured at right angles to a tangent to an inflection point between tooth back and tooth base, between this inflection point and the opposite tooth face is greater than a quarter of the pitch.

A method and an apparatus for producing a reinforcement mesh. Here, a reinforcement fiber strand is firstly saturated with a resin (H) and cured to form a cured, fiber-reinforced strand material. The strand material present as an endless material is then cut lengthwise into bars, which are then used as longitudinal bars or transverse bars for forming the reinforcement mesh. A connecting material is used at each intersection point between a longitudinal bar and a transverse bar and is dispensed in liquid form at the intersection point or is liquefied and then cured at the intersection point. A fixed connection is thus created between the longitudinal bars and the transverse bars at the intersection points. Between the intersection points, the longitudinal bars and the transverse bars have portions that are free of connecting material.
