Methods for bending stretched synthetic resin sheets |
摘要 |
Methods and apparatus are disclosed for bending mono-axially or bi-axially stretched sheets of a thermoplastically deformable synthetic resin by heating one side of the sheet above the softening temperature of the resin while the temperature on the other side is beneath the softening temperature, whereupon the resin sheet bends by itself or can be bent with forming tools.
