A replaceable mold part according to the present invention comprises: a depressed portion remained near a cavity; and a detachable portion, the detachable portion having a marking portion or a gas-releasing function, and being caught by a catch mechanism within the depressed portion. When a magnet is brought into proximity of the detachable portion through the cavity and an external magnetic field is applied, a magnet support portion's position is shifted from the fixed location to the released location within the depressed portion so that the catch mechanism of the detachable portion by the depressed portion is switched from the fixed state to the released state, thereby the detachable portion can easily be removed from the depressed portion through the cavity.

A process for manufacturing a rubber patch comprising a radiofrequency transponder, the patch having a first layer and a second layer, the method comprising moulding and vulcanizing a first layer, the exterior surface of which comprises a cavity able to receive a radiofrequency transponder, placing a transponder in the cavity, and then placing and vulcanizing a second layer in order to embed the transponder between the two layers.

This disclosure concerns a master model for the production of a mold, comprising: (a) a first part, a second part comprising a textured surface; wherein the first part and the second part are connected.

The present invention relates to a carrier for adhesive, with the carrier being configured to be attached to a surface having a topology, in particular a time variable topology, such as a part of a human or animal body. The invention further relates to a use of the carrier, to a method of activating a carrier and to a method of making a carrier.

A clamping device has an actuator that moves linearly and is actuated by a drive. A pivoting clamping element is operatively connected, via a toggle lever mechanism, with the actuator. The toggle lever mechanism includes a drive-side adapter and a hand lever-side adapter. The drive side adapter and hand lever side adapter can be adjusted relative to one another to define an opening angle of the clamping element. One of the adapters has a profiled bar extending in a direction of actuation. The other adapter has an insertion region to accommodate the bar. A fixing element is provided in one of the adaptors to define the location of the adapters relative to one another. The fixing element can be clamped against the profiled bar and also against an insertion region.

A method for extrusion coating or extrusion casting, a polymer sheet (4, 5) produced thereby, a roller (2) for use in extrusion coating or extrusion casting, and an apparatus comprising said roller (2), in which micro- and/or nanostructures provided on the surface of the roller (2) are transferred to the polymer sheet (4, 5), and which is applicable to the extrusion coating or extrusion casting of all types of thermoplastic polymer.

A mold for casting a micro-scale dry adhesive structure includes an upper surface including a first cavity having a first depth, a negative pattern for an array of micro-scale structures defined in a surface of the first cavity, and at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures, the at least one second cavity defining a negative pattern for a standoff of the micro-scale dry adhesive structure.

Described is a resinous structure derived from fluorine-containing polymers useful as a mold having excellent dimensional stability.

An apparatus forms a pattern of an imprint material by curing the imprint material in a state in which the imprint material on a pattern formation region of a member, where a pattern is to be formed, is in contact with a pattern region of a mold. The apparatus includes a dispenser for placing the imprint material on the pattern formation region of the member and a non-pattern formation region of the member, outside the pattern formation region, a detector for detecting the non-pattern formation region in a state in which the imprint material has been placed on the pattern formation region and the non-pattern formation region by the dispenser, and a controller for performing processing for determining an abnormality in the dispenser based on a detection result of the non-pattern formation region by the detector.

A method is for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires, the molding area of which molds a segment of the tread profile of a tire to be vulcanized, including the steps: creating a rigid model segment having a casing-like tread surface; milling the profile positive of the tread into the casing-like tread surface of the model segment to obtain the master model; creating a flexible impression from the master model; creating a rigid plaster cast from the impression to form a casting core segment; casting all of the annular, placed-together casting core segments with an aluminium-magnesium alloy to obtain a vulcanizing mold, subsequently divided into profile segments. A plasma coating is applied to the tread of the model segment, into which the profile positive of the tread is subsequently milled to obtain the master model. Plasma coating gives the master model a defined roughness.
