Embodiment Construction

[0385] As used herein, the term "and / or" means "and" or "or", or both.

[0386] As used herein, a noun followed by an s includes a singular or plural form of that noun as may be appropriate.

[0387] Preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0388] We recognize that there is an advantage in providing a forming apparatus (1) which moves the two sets of tool parts (in use (whether in continuous use or stop and start motion, hereinafter referred to as a "continuous" process) ) continuously or uninterruptedly arranged forming tools (11)), so that one forming tool (11) reaches the condition of cooperating with the complementary forming tool (11), thereby pressurizing the cooperating forming tools, or relying on The allowable pressure required to shape the material holds the cooperating forming tools and then separates the forming tools. The process can also be performed at controlled temperature.

Abstract

The present invention relates to method of forming a material, including the following steps: presenting formable materials to a space from where the material can be carried by and / or between opposing surfaces of the space, as the opposing surfaces advance in an advancing direction; pressurizing, as the opposing surfaces advance, the material between the opposing surfaces in a reduced space between the opposing surfaces defining at least in part a pressure forming zone; the reduced space between the opposing surfaces being maintained at least substantially constant until such time as the formof at least one of the opposing surfaces is profiled into the material and is retainable thereon; thereafter releasing the now profiled material from between the opposing surfaces, as the space increases between the opposing surfaces as the surfaces advance. The relative movement between adjacent tools of at least one set of forming tools over the zone before the pressure forming zone is only towards the forming tools of the other opposing surface.

Description

technical field [0001] The present invention relates to an apparatus for forming material and to products which may be formed by the apparatus. Background technique [0002] Different kinds of forming methods (whether forming under the influence of pressure only, such as drawing (deep drawing or shallow drawing) and embossing, or forming under the influence of pressure and temperature, such as injection molding, blow molding, extrusion , vacuum forming, thermoforming, pressure forming, compression molding (such as compression molding of rubber or cross-linkable materials), vacuum forming combined with material extrusion, thermoforming combined with extrusion and / or vacuum forming , calendering and subsequent processing and similar forming processes) lies in the need to ensure that the equipment has the following capabilities: [0003] (i) meet the required tolerances; [0004] (ii) meet its operating conditions without failure; [0005] (iii) will not interfere destructiv...
