摘要：Thermoforming apparatus adapted to accommodate molds of different lengthsto form molded parts in a horizontal web comprises a vertically movable support. A moldbase assembly carried by the support includes a flat-topped rectangular basic mold basesecured horizontally to the support. A plurality of flat-topped straight mold baseextension segments are removably secured together in side-by-side relationship forminga rectangular array. The array is removably secured to the basic mold base and support.A first vertically movable straight gate is secured to the free end of the basic mold base.A second vertically movable straight gate is removably secured to the segment at thefree end of the array. Any one or more segments along with the second gate can beremoved from the mold base assembly without disturbing the basic mold base andremaining segments. The second gate can then be attached to the segment at the freeend of the shortened array. A manifold for passing a fluid coolant through the basic moldbase and segments is provided with detachable branches connected to as manysegments as there are in an array thereof at any given time. A cooperating mold assistbox over the mold base assembly contains removable assist bars which hold the web inplace during molding. The box has a fixed end wall and movable end wall cooperating

with the gates to hold the web in place during molding. By means of the movable endwall the box can be adjusted in length to conform with the length of the mold baseassembly.
