摘要： A method of forming shaped products from thermoplastic materials, by bending a plastic strip with the sued of sahper members which reciprocate both lengthwise and crosswise relative to a continuously moving strip. A device for carrying said method into effect is characterized by the fact that said sahper members are fixed to structural components which are imparted reciprocating motion from a drive both lengthwise and crosswise relative to the strip under treatment.
