Abstract
A process for making moldings with areas of marked final deformation from highly sensitive materials, such as tangled-fiber fleeces, in which the flat material is molded in the softened state between press molds. Prior to the actual molding process and independent of the desired molding of the final molding in a particular area and without any precompression of the material, the material is mechanically drawn between the corresponding press molds to such an extent that the resulting material flow roughly corresponds to the feed requirement for the final molding operation. The necessary auxiliary device comprises one or more push-rods with ram heads, which can be brought between the press molds when the press is in the open position and can be moved in the desired directions in the manner of an automated human fist.
Claims13
In an apparatus for molding three-dimensional moldings from flat materials in which the flat material is molded between closeable and openable, opposed press molds in a softened state, the improvement comprising:
- an auxiliary device movable backward and forward between the open press molds, the auxiliary device comprising a frame structure, a push rod, and a ram head attached to the push rod;
- the frame structure movable backward and forward between the open press molds;
- at least one push-rod pivotally mounted at a first end on the frame structure, a second free end of the push-rod opposed to the first end being extensible into contact with the surface of the material to be molded to press such material into one of the press molds;
- and
- wherein the movement direction of the push-rod forms an angle with the direction of movement of press molds.
In an apparatus for molding three-dimensional moldings from flat materials in which the flat material is fed in a given direction and is molded between closeable and openable, opposed press molds in a softened state, the improvement comprising:
- an auxiliary device movable backward and forward between the open press molds, the auxiliary device comprising a frame structure, a push-rod and a ram head attached to the push-rod;
- at least one push-rod pivotally mounted at a first end on the frame structure, a second free end of the push-rod opposed to the first end being extensible into contact with the surface of the material to be molded to press such material into one of the press molds;
- wherein at least one arm is pivotally connected to the auxiliary movable device in a direction of the intended flow of the material so that the point of contact between the ram head and the surface of the material to be molded is displaced in the feed direction of the material relative to a center of the pivoting movement of suspension of the ram to the auxiliary movable device.
