Abstract: The invention relates to a device and a method for testing materials, and is characterized in that the device comprises application units (2) for interaction modules (1) and an exchange system for the interaction modules, and the device is designed such that the application units (2) automatically feed interaction modules (1) to the exchange system after a control signal and the exchange system is designed to feed the interaction modules to a test position.

Abstract: The invention relates to a device for stretching film sections in a monoaxial or biaxial manner, preferably by way of a tenter frame, for films made substantially of polymers, wherein a square or rectangular section of a such film is seized at 4 sides by at least two tenter hooks each, designed as regards improved stretching such that the upper tenter hook part (11) is mounted in an articulated fashion on a rotational axis located outside the film to be stretched, and specifically such that the lower, fixed tenter hook part (13) carries the joint, while the upper tenter hook part (11) is designed so as to pivot upwards and at least one cylinder (14) is disposed rotated by 90° for applying the tensioning power and thus applies the tensioning power to the upper pivotable tenter hook part (11).

Abstract: In a device for testing the purity of a plastic melt by plasticizing a melt and pressing a defined quantity of the melt through a screen with a defined size and porosity while simultaneously measuring the melt pressure, a changeover valve with two positions is provided—namely a working position for the test operation and a cleaning position—and furthermore a screen changer is provided, which has at least two screen positions in the interior of the testing device which is heated, namely a pre-heating and a testing position, in addition to a respective insertion and removal positions.

Abstract: In an apparatus for measuring the viscosity of plastic materials including a heatable housing structure, enclosing a controllable material pump for generating a certain material flow, a plurality of capillaries, a melt distributor is provided in the supply line of the material from the material pump to the capillaries with which the material can be directed to either of the plurality of capillaries and each capillary is provided with a pressure and a material temperature sensor providing the values needed for determining the viscosity of the material.
