TRIM TOOL WITH ADJUSTABLE TRIM CENTERS
20230051517 · 2023-02-16 ·

A thermoforming trim tool which comprises a punch side and a die side. The punch side moves to the die side in order to trim molded articles from a heated thermoforming sheet that is disposed therebetween. While the punch side of the tool comprises a plurality of punches, the die side of the tool comprises a plurality of dies, and both the punches and the dies are engaged with upper mount plates. Each of the upper mount plates is engaged with a lower mount plate via one or more location keys. Each of the location keys is configured to provide that the upper mount plates are shifted a pre-determined distance relative to the lower mount plate, thereby providing trim centers which are adjusted to account for pre-determined shrinkage in the sheet.

METHOD AND APPARATUS FOR THERMOFORMING AN ARTICLE

A method for thermoforming an article includes extruding a sheet of material, conditioning the sheet with a roller, thermoforming the sheet to provide a web, and cutting the web to provide the article.

DEVICE FOR SEPARATING A DEEP-DRAWN JAW-SPANNING DENTAL APPARATUS OF THERMOFORM FILM

A device for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film that includes: a separating element for thermally separating the deep-drawn thermoform film and simultaneously refining, the separated deep-drawn thermoform film; a heating means for regulating the heating of the separating element so as to increase the temperature of the thermoform film substantially to at least its glass temperature; a support for supporting the deep-drawn thermoform film relatively movable with respect to the separating element; a moving mechanism for moving the separating element along a separation contour of the deep-drawn jaw-spanning dental apparatus relative to the support; and a control unit adapted to control the heating means and the moving mechanism based on the separation contour.

METHOD AND APPARATUS FOR PROCESSING A FORMABLE MATERIAL

A method and apparatus for processing a formable material having at least first and second relatively repositionable units. The first unit has a sheet die, with the second unit having a rotary drum with a peripheral forming surface for receiving flowable material from the sheet die. The first and second units can be selectively changed between an operating relationship and a setup relationship, with the latter causing at least one space to be defined/enlarged and within which an operator can maneuver to gain access to a region of at least one of the first and second units. With the first and second units in the operating relationship, moldable sheets can be processed by causing the moldable sheets to be applied, and conformed, to the peripheral forming surface on the rotary drum.

A method for producing an element of a capsule, the capsule being intended to contain a product having at least one component that can be extracted by means of an extraction fluid, comprises the step of obtaining at least one preparatory zone intended to define, during use of the capsule, a passage for the extraction fluid, so that the extraction fluid can pass through the capsule in order to extract said component. The preparatory zone is obtained by means of a cutting operation carried out before the capsule is filled with the product and after the capsule element has been formed. The cutting operation is carried out by means of a blade element.

The gripper jaw elements are provided on a gripper head part of the gripper. The gripper head part of the gripper is movably mounted, at least with one degree of freedom, relative to the gripper chassis.

PRODUCTION PROCESS OF A COMPOSITE PRODUCT
20210379801 · 2021-12-09 · ·

Production process of a composite product (1) comprising a core (2), a first layer (3) comprising a sheet impregnated with a solid polyurethane material, and a polymer-based film (7) applied to the first layer (3), wherein the process comprises: producing a semi-finished product comprising the core (2) and the sheet impregnated by a liquid mixture precursor of the solid polyurethane material; adhering the film (7) to a first half-mould (11) by applying a depression between the film (7) and the half-mould (11); pressing two half-moulds (11, 12) against each other with the semi-finished product interposed between two shaping surfaces (13), so that the film (7) comes into contact with the liquid mixture; with the semi-finished product in the mould, thermosetting the liquid mixture to transform it into the polyurethane solid material so that the film (7) firmly adheres to the first layer (3) and thus producing the composite product (1).

METHOD AND DEVICE FOR APPLYING A MATERIAL TO A SUPPORT

Methods and apparatuses for mounting a material (1) on a carrier (6) are provided. To this end, the material is arranged on a porous layer (2) of an air bearing arrangement (2, 3).
