Vacuum-forming and stacking machine for deep-drawn thermoplastics - has independent axial and servomotor driven tilt motions of mould table, for improved control

摘要

Vacuum-forming and stacking machine for deep-drawn thermoplastics with a mould table (27), axially movable and tiltable about a transverse axis, in which the table is swung to the stacking position by a servomotor (21,22), specifically, independent of the axial movement. ADVANTAGE - Avoids increasing the speed of tilting when the axial mould opening speed is increased, giving improved control over Patent DE3346628. It is said to avoid difficult and precise design/adjustment of cams and linkage to change the relation between the axial and tilting motions and avoid dismantling for the purpose.
