The invention relates to a method for producing flexible tube bodies () for packaging tubes from a film substrate () which has a print, preferably on an outer side (), and which has or consists of at least one weldable plastic layer and which comprises a first longitudinal edge side (), which extends in a longitudinal direction, and a second longitudinal edge side (') parallel thereto and spaced apart therefrom, wherein the film substrate () is shaped by shaping means () to form a tube, and the two longitudinal edge sides (′) are in particular welded to one another with the formation of a longitudinal weld seam, wherein a strip () is arranged, in the region of the abutment point and/or of the longitudinal weld seam, in the interior () of the film substrate () shaped to form the tube and is connected, in particular welded, to the longitudinal edge sides (′) at least in certain regions or portions. According to the invention, prior to the formation of the longitudinal weld seam, at least one longitudinal edge side (′) is shaped, in particular cut, in such a way that, in the film substrate () shaped to form the tube, the longitudinal edge sides (′) bear against one another, in particular in abutting fashion, radially only in the region of the outer side () with at least one tip () formed by the shaping operation.

The invention relates to a welding device () for producing tubular bodies by the edge-side welding of two substrate edges (), in particular two laminate edges, said welding device having a continuous, circulating first contact belt () for coming into contact with the substrate (), and an energy source () for providing welding energy. According to the invention, the first contact belt () has a seamless polyimide contact surface () for coming into contact with the substrate ().

Welding device for producing tubular bodies

A thermal analysis device comprising a replaceable sensor that can be contacted via a contact element of an electrical contacting means, a heating element and a cooling element. The contact element(s) is thermally connected with the heating element and can be heated essentially independently of the operating state of the cooling element even when no sensor is mounted to the device.

Thermal analysis device

In a dynamic mechanical analysis, a test specimen is coupled to an excitation device by a holder device. An excitation force made up of a static pre-tensioning force component and a time-variable force component is applied to the test specimen, and a deformation of the test specimen is measured by one or more displacement sensors. In a test phase an excitation force is applied to the test specimen, while at least one decision parameter is determined. The decision parameter is indicative of a degree of slack in the coupling of the test specimen. Based on the comparison between the decision parameter and at least one reference value it is determined whether or not the test specimen is coupled to the excitation device in a completely slack-free state, so that any measured physical values will not be subjected to errors caused by an insufficient amount of the pre-tensioning force.
