Abstract: Plastic profiles are produced by a pultrusion method. For this, a mold is moved periodically relative to the stationary plastic profile and said profile is held by a holding means and transported away. In particular, the starting and the stopping of the method are problematical, since a tensile stress must be applied, by which both “slack” fibers and “rigid” profiles can be drawn through the mold. The invention creates a method and a device for simple and reliable manufacture of plastic profiles. For this, it is provided that at least one cross section of a receiving space of the at least one holding means is changed along a longitudinal axis of the holding means in order to grasp a reinforcement and/or the plastic profile.

Abstract: A method and a device for fault-free production of individually curved plastic profiles. This is achieved in that the mold and the holding means are moved in opposite directions on the plastic profile, wherein the plastic profile is moved alternately by the mold and the holding means in a production direction with different movement patterns.

Abstract: A rest for a mattress support system and which serves for sensory training of a person, and a method for sensory training of a person. This rest has a multiplicity of actuatable micro-stimulating elements for producing sensory stimuli. These elements are assigned to the rest. Using a control device, the person can actuate the micro-stimulating elements during the training. Moreover, this control device serves to generate a feedback signal in response to the sensory stimuli.

Abstract: Straight plastic profiles from a plastics material and a continuous reinforcement are predominantly produced continuously in a strand, usually by the pultrusion method. As the plastic profile is pulled through a mold, only straight plastic profiles are formed in known pultrusion methods. In the production of plastic profiles using semi-finished products or complex fibrous constructions, congestion of the fibrous constructions or of the semi-finished products, and thus solidification of the material, may arise when entering the mold, such that the process has to be stopped. A method and a device for the simple production of individually molded plastic profiles is provided in that the mold is formed from at least two mold parts that in relation to the cross section of the plastic profile are split and are moved in a temporally offset manner counter to a production direction of the plastic profile along a portion of the plastic profile.

Abstract: A core (14) which is typically held in front of the mold (13) is required for producing hollow plastic objects (10). This does not allow for a transverse reinforcement (11) which is formed from a prefabricated reinforcement tube to be pulled over the core (14). A method and device is provided for the core (14) to be held behind the mold (14) when viewed in the production direction (17). In this case, the front end (15) of the core (14), which is located in front of the mold (13), remains free, such that a transverse reinforcement (11) that has been formed from a prefabricated reinforcement tube can be pulled over the free front end (15) of the core (14).

Abstract: A method for producing an object or component, which is at least partially formed from plastic, by supplying energy for solidifying the plastic of the object or component to the plastic to be solidified by at least one energy conductor, such as an optical fiber, in the component to be produced, and the solidification of the plastic can be accelerated by the direct energy introduction into the object or component to be produced.

Abstract: In the pultrusion of reinforced plastic profiles in strand form, the strands of the reinforcement are brought together in a positioning device and subsequently embedded in the plastic. The pulling of the strands of the reinforcement through the positioning device leads to an unwanted contraction and uncontrolled positioning of the reinforcement in the plastic profile. The invention envisages forming the positioning device by multiple successive positioning means, of which at least some positioning means can be periodically moved forward in the direction of production and also moved back counter to the direction of production. As a result, there is an alternating tensioning and compression of individual regions of the reinforcement. This makes exact positioning of the reinforcement in the plastic profile possible and prevents contraction of the reinforcement.

Abstract: A method and device in which at least part of a mold is moved periodically relative to the stationary thin-walled plastic profile and the thin-walled plastic profile is held by at least one holding means or gripper, which comprises a core and an outer holding part, whilst the mold is moved along the thin-walled plastic profile, which is stationary relative to said mold. Plastic material objects, in particular plastic profiles, are produced predominantly in a strand, preferably using the pultrusion method. In this case, the plastic profile is pulled through a mold. As a result of the plastic profile being pulled through the mold by a take-off device, it is only possible to form plastic profiles which withstand the force or the pressing pressure of the take-off device. Consequently, only plastic profiles which comprise sufficient wall thicknesses have been producible up to now.

Abstract: Plastics articles with continuous reinforcement strands are normally produced by pultrusion. Pultrusion methods are known for producing straight or curved plastics profiles. It has not hitherto been possible for reinforced plastics articles of more complex form to be produced by pultrusion methods. The invention provides a pultrusion method in which a part of a curved plastics article serves, together with a mold (15), for the pultrusion of a reinforced plastics article. In this way, it is possible for complex plastics articles, for example a plastics pipe (10), to be produced by pultrusion.

Abstract: In the production of elongate plastic profiles (10), which usually takes place by the pultrusion process, the cured plastic profile (10) emerging from a die (14) is pulled through the stationary die (14) by a take-off device. This process only makes it possible to produce straight plastic profiles (10). The invention envisages producing curved plastic profiles (10) by using a die (14) corresponding to the curvature of the plastic profile (10). For moving the cured part of the plastic profile (10) out of the die (14), it is provided that the die (14) is moved back step by step in relation to the stationary plastic profile (10) counter to the direction of production (19). In order that the plastic profile (10) remains stationary in relation to the die (14) as this takes place, it is securely held outside the die (14) by a holding means (20) during the moving back of the die (14).

Abstract: The invention provides as a connecting element at least one flexural pull element (29) disposed between the pivotable back element (13) and leg element (15) of the support (12). Such a flexural pull element, which can be a cord or belt, for example, can be arranged in a space-saving manner under the support (12) and integrated in a frame (11) of the bed or cot. Thus, no space is taken up by the pull element beneath the frame (11). The invention thereby provides a connecting element of simple and space-saving design which allows for the simultaneous pivoting of the back element (13) and leg element (15) of the support (12).

Abstract: The invention here provides a support, in particular a mattress or a part of a mattress, that preferably has a number of layers (11, 12) of elastic tubes (13). The tubes (13) of each layer (11 and 12) extend parallel to one another. The tubes (13) of different layers (11, 12), however, extend in a preferably crosswise manner to one another. Due to the elastic tubes (13), the inventive support or mattress provides a high degree of sitting and lying comfort with amazingly simple means.

Abstract: The invention is a profiled bar, in particular sprung bars, in which a reinforcement of both synthetic fibers and natural fibers is embedded in a plastic matrix. The proportion of synthetic fibers can be reduced by using natural fibers derived from regrowing raw materials. This improves environmental compatibility and makes it easier to dispose of such sprung bars. The sprung bars are used in particular to form bottom sprung supports for furniture for sitting and lying on, and in particular for slatted frames.
