Device and process for the production of angled or double standing seams

Abstract

The disclosure relates to a device for seam closing single or double standing seams. The device includes a guiding element and a seaming element. The seaming element includes at least two seam forming wheels on one side and at least two seam forming wheels on an opposite side. The seam forming wheels are rotatably mounted and the guiding element is slidably connected to the seaming element by positioning rods, with at least one of the positioning rods serving as a bearing pin in at least one region. The guiding element and the seaming element are twistable with respect to each other. A method for the manufacture of single or double standing seams is provided. In addition, the disclosure relates to the use of a device according to the invention for cutting open or removing existing standing seams.

1 . A device for seam closing single or double standing seams, the device comprising:
 a guiding element; and   a seaming element, wherein
 the seaming element comprises a set of seam forming wheels on one side and a set of seam forming wheels on an opposite side,

         2 . The device according to  claim 1 , wherein the set of seam forming wheels on one side is configured to manufacture an angled seam, and the set of seam forming wheels on an opposite side is configured to manufacture double standing seams. 
     
     
         3 . The device according to  claim 1 , wherein the guiding element comprises a force transmission unit. 
     
     
         4 . The device according to  claim 3 , wherein the force transmission unit comprises:
 a drive element not linked to a power supply system,   a drive shaft with a receiving pin,   a transmission, and   at least two gearwheels.   
     
     
         5 . The device according to  claim 1 , wherein the seaming element comprises at least two gearwheels, wherein the at least two gearwheels are attached to the seaming element and the at least two seam forming wheels are rigidly interconnected and have a common axis of rotation. 
     
     
         6 . The device according to  claim 4 , wherein the at least two gearwheels of the force transmission unit and the at least two gearwheels attached to the seaming element interlock in a closed state of the guiding element and the seaming element. 
     
     
         7 . The device according to  claim 1 , wherein the at least two gearwheels attached to the seaming element and the two opposite sets of seam forming wheels are rigidly interconnected and have a common axis of rotation. 
     
     
         8 . The device according to  claim 1 , wherein the seaming element comprises at least one stabilizing wheel on the one side and at least one stabilising wheel on the opposite side, the stabilizing wheels being rotatably mounted, with the axes of rotation being oriented orthogonally to a direction of lock-seaming. 
     
     
         9 . The device according to  claim 4 , wherein the drive element comprises an electric motor not linked to a power supply system is a commercially available cordless drill. 
     
     
         10 . The device according to  claim 3 , wherein the force transmission unit comprises a clamping device for commercially available drills. 
     
     
         11 . The device according to  claim 1 , further comprising at least one cutting wheel. 
     
     
         12 . The device according to  claim 11 , wherein the at least one cutting wheel is attached by means of receiving holes. 
     
     
         13 . A process for manufacturing double standing seams with a device that includes a guiding element and a seaming element, wherein the seaming element comprises a set of seam forming wheels on one side and a set of seam forming wheels on an opposite side, and the guiding element is slidably connected to the seaming element by positioning rods, with at least one of the positioning rods serving as a bearing element in at least one region, wherein the guiding element and the seaming element are twistable with respect to each other, the process comprising:
 manufacturing an angled seam, with the device being located at an angled seam position;   subsequently pivoting the seaming element from the angled seam position into a double seam position;   manufacturing a double standing seam, with the device being located at the double seam position.
