Patent number: 11446886Abstract: 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.Type: GrantFiled: May 3, 2018Date of Patent: September 20, 2022Assignee: Thomas GmbH + Co.

Patent number: 10456998Abstract: 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.Type: GrantFiled: June 30, 2015Date of Patent: October 29, 2019Assignee: Thomas GmbH + Co.

Method and device for producing a hollow plastic object having at least one transverse reinforcement
Patent number: 10052829Abstract: 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).Type: GrantFiled: June 12, 2013Date of Patent: August 21, 2018Assignee: Thomas GmbH + Co.

Publication number: 20170173851Abstract: 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.Type: ApplicationFiled: March 1, 2017Publication date: June 22, 2017Applicant: Thomas GmbH + Co.

Publication number: 20160339604Abstract: 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.Type: ApplicationFiled: January 7, 2015Publication date: November 24, 2016Applicant: THOMAS GMBH + CO.

Patent number: 9393741Abstract: 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.Type: GrantFiled: October 19, 2012Date of Patent: July 19, 2016Assignee: Thomas GmbH + Co.

Publication number: 20140031458Abstract: During the production of reinforced and non-reinforced components (45) made of plastic, the plastic must be solidified after the molding. For this purpose, energy must be supplied to the component (45) to be produced. This has heretofore been performed by heating the mold (47) for producing the component (45). The energy introduction into the component (45) to be produced is thus limited, which results in long solidification times of the plastic, above all in the case of larger and more voluminous components (45). The invention provides supplying the energy for solidifying the plastic of the component (45) to the plastic to be solidified by at least one optical fiber (51) in the component (45) to be produced. The solidification of the plastic can be accelerated by the direct energy introduction into the component (45) to be produced.Type: ApplicationFiled: August 9, 2011Publication date: January 30, 2014Inventor: Klaus Jansen
