Abstract
Improvement for forming machine by preventing the softened thermoplastic material sheet from dangling and unevenly stretching between a pair of clamp chains, which are extended on a plurality of sprocket wheels to be intermittently driven so that the upper run thereof may receive and keep the sheet stationary in the waiting zone of the machine when the male and female die boxes are contacted for molding and then feeding the sheet between the separated die boxes. The improvement comprises a plurality of longitudinally elongated supporter means such as endless strings or a series of small discs arranged longitudinally close with each other in said waiting zone, and a plurality of bores formed in the lower die box for blowing air in the molding zone.
