Auto-aligning vacuum presses, that include a mobile assembly with a first platen, a vacuum docking station with a second platen, a first locating device to guide the mobile assembly to a desired location along the Y-axis as the mobile assembly moves along the X-axis into the vacuum station, and a second locating device to guide one of the first and second platens along the Z-axis into sealing engagement with the other platen.

A plant for reshaping plastic preforms into plastic containers, includes a heating device for heating the plastic preforms, and a device for reshaping the plastic preforms into the plastic containers, arranged downstream of the heating device in the transport direction of the plastic preforms, wherein the reshaping device includes a transport device, which transports the plastic preforms along a predefined transport path and wherein the transport device has a station carrier on which a multitude of reshaping stations are arranged, each having blow mold devices each arranged on blow mold carriers. The reshaping device includes a changing device, which is suited and intended for at least removing and/or attaching the blow mold devices to the blow mold carriers, wherein this changing device is further suited and intended for at least removing and/or attaching the changeable element to the heating device.

A device for turning over molds is provided that can reduce the wear of turning over wheels and supporting rollers even when the speed for transporting a flask or the speed for turning it over increases. A pair of turning over wheels (5) are attached to respective sides of a turning over roller conveyor (4), on which a metal flask (3) is mounted. The outer surfaces of the wheels are supported by respective pairs of supporting rollers (6). A driving roller (9) is provided on one or both of the wheels. The supporting rollers are flangeless. Two pairs of side rollers (10) abut the side surfaces of the wheels so as to prevent them from moving in the direction in which the flask is transported. The side rollers are preferably configured so that their surfaces that contact the wheels are formed as arcs.

The present invention is a method and apparatus for quick and easy rubber sleeve exchanges on chill rolls, such as are used in film extrusion processes. The apparatus includes chill roll or mandrel, a rubber sleeve covering the exterior face of the mandrel, an automated cantilever system, and an air booster. The rubber sleeve is easily removed by tilting the mandrel and inserting a layer of air between the rubber sleeve and the mandrel, thereby allowing the sleeve to slip off the mandrel and allowing for a new rubber sleeve to be placed onto the mandrel.

A tooling system may comprise a tool scanner, a tool database, and a user interface device. The tool scanner may be configured to scan a tool identifier on a tool. The tool database may have tool information associated with the tool identifier. The user interface device may be in communication with the tool scanner and the tool database. The user interface device may receive tool information from the tool database in response to the scan by the tool scanner, concurrently display a tool issue description and a tool issue image from the tool information of the tool database, receive a tool area selection with respect to the tool issue image, and provide access to a tool issue history from the tool database in response to the tool area selection.

A system for transforming plastic parisons to plastic containers with a transport device which transports the plastic parisons along a predetermined transport path, wherein the transport device has a movable station support disposed at least indirectly on a stationary base support on which a plurality of transforming stations is disposed. The transforming stations each have blow mold devices which each form cavities within which the plastic parisons can be transformed into the plastic containers and these blow mold devices are each disposed on blow mold supports. The system has a changing device which is suitable and intended in order, in a changing mode of the system, at least to remove the blow mold devices from their blow mold supports and/or to dispose blow mold devices on the blow mold supports, and wherein, during a further mode of operation which differs from the changing mode, this changing device is suitable and intended for carrying out a treatment operation on at least one working element intended for the system.

An apparatus for shaping plastics material pre-forms into plastics material containers has a conveying device which conveys the plastics material pre-forms along a pre-set conveying path. The conveying device has a movable station carrier arranged at least indirectly on a stationary base carrier and on which a plurality of shaping stations are arranged. The shaping stations have blow moulding devices which form cavities inside which the plastics material preforms are shaped to form plastics material containers. The blow moulding devices are arranged on blow mould carriers. The apparatus has a changing device suitable for removing at least the blow moulding devices from the blow mould carriers and/or arranging blow moulding devices on the blow mould carriers. A changing device has a gripping device for gripping the blow moulding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three different axes.

A press for producing a molded part from pourable material has an apparatus for driving a die that includes a cylinder unit having a cylinder housing and having a cylinder piston. The cylinder housing is the actuator of the cylinder unit and the cylinder piston is the stator of the cylinder unit.

The present invention relates to a novel device to manufacture polyurethane foam boards used in structurally insulated panel known as insulated building material press. The press enables the application of pressure across a large area while foaming and curing polyurethane under pressure, curing glue or otherwise bonding materials into a finished product or to form multiple panels in a single press at the same time. The building material press can be used to manufacture multiple structurally insulated panels simultaneously. The press is mobile and can be transported by means of a vehicle to a remote location.
