Methods, plate elements and heat/enthalpy exchangers. a) perforating an unformed plate element with defined outer dimensions in any desired area and in any desired dimension; b) covering at least one side of the unformed plate element with a thin polymer film with latent energy exchange characteristics and; c) forming the plate element into a desired shape and a pattern of corrugations and/or embossing. The operations b) and c) may be performed in a different order. For instance, when the plate element is made out of plastic, b) may be performed before c) whereas, when the plate element is made out of aluminum (or plastic), c) may be performed before b). Operations a) and/or b) and/or c) may also, in certain embodiments, be combined.

A method of manufacturing a plastic container having a curled rim (320) comprises the steps of providing a sheet of plastic material; drawing a portion thereof into a mould (120) to form a bottom and wall (310′) of the container, leaving a surrounding portion of material to form a rim (320) of the container; cutting the rim loose from a remaining portion of material; and curling the rim. In the curling step, an inner part of the rim is supported by a supporting member while an outer part is pressed by a pressing member (230) moving relative to the supporting member for the rim to be bent around the supporting member.

A unitary elastic mold and cutter combination configured to mold and cut moldable material is disclosed herein. The mold and cutter combination comprises an elastic mold cavity having an elastic bottom wall with an embossed inner surface and an elastic sidewall extending from and unitary with a perimeter of the bottom wall. An elastic cutting blade extends from and is unitary with the sidewall of the mold cavity and is configured to cut moldable material and maintain a substantially consistent perimeter upon cutting. The cutting blade comprises a cutting edge disposed between an inner cutting blade surface and an outer cutting blade surface. The mold and cutter combination may have an elasticity sufficient to release molded material therefrom by hand stretching, wherein the cutting edge, inner cutting blade surface, and the inner surface of the sidewall of the mold cavity are stretched by an amount sufficient to release the molded material.

A method of manufacturing a sole structure includes providing a plate within a cavity of a mold. The plate includes a base and a rib, and the base includes a first surface and a second surface. The first surface faces the upper, the second surface faces away from the first surface, and the rib projects from the second surface of the base. Moreover, the method includes providing a preform bladder member within the cavity of the mold, wherein the preform bladder member including a first member and a second member. The method additionally includes forming a bladder from the first and second members using the mold. Also, the method includes attaching the first member to the plate using the mold. Attaching the first member to the plate includes shaping the first member according to surfaces of the rib.
摘要:
The invention relates to a process for producing thermoformed articles such as food packagings or parts thereof with a mechanical weakening between adjoining functional areas, which, for utilization by a user, can be at least partly separated at the mechanical weakening, in a thermoforming die having an upper die and a lower die, the mechanical weakening being introduced with a three-dimensional extension during the period of time during which the material to be formed is located in the thermoforming die, and a thermoforming die for implementing the process.
