Abstract (en)
The invention provides a chair for railroad rails. The tie-plate (1) is partly enveloped in synthetic resin (4). By a special construction of the chair (no sharp edges) and injection moulding it has proved possible to obtain a sufficiently strong envelope of synthetic resin (4). The envelope (4) is made of a glass-fibre-reinforced polyester injection-moulding material.
