The invention relates to a method for at least partially remachining or replacing a reinforcement element (10) of a fibre composite structure (8). In a first method step, at least one fibre layer (11) is arranged on a surface section of the reinforcement element (10) and/or at least one replacement section of the reinforcement element (10) of the same material and same layer structure is arranged on a surface reinforcement section of the fibre composite structure (8). In a second method step, at least a pressure mat (4) adjusted to the contour of the reinforcement element (10) is disposed above the at least one fibre layer (11) and/or the at least one replacement section of the reinforcement element (10), wherein the at least one pressure mat (4) is supported and fixed in a nominal position by a fixing frame (3) adjusted to the contour of the reinforcement element (10). In a third method step, the at least one pressure mat (4) is then acted upon by a pressure medium in order to press the same against the reinforcement element (10) and the fixing frame (3). In a fourth method step, a hardening of the at least one fibre layer (11) and/or the at least one replacement section of the reinforcement element (10) is carried out. The invention further relates to a corresponding connecting device (1) for carrying out the method.

The invention relates to an electric hot wedge (1) for a welding device for the seam-like connecting of plastic webs, having a welding wedge (2) and a welding wedge attachment (3) made of metal, wherein the welding wedge (2) comprises at least one electric heating resistor (13) having a heating conductor (16), which is bonded to a ceramic carrier (15) as a conductive layer (12) and is preferably protected by a ceramic cover layer. According to the invention, the welding wedge attachment (2) has a support structure (28) made of metal on the side thereof, which substantially extends across the entire length and/or width of the electric heating resistor (16) and which mechanically stabilizes the carrier (15) of the heating resistor (16).
摘要:
A machine for packaging products in a heat-sealable film comprises a longitudinal welding group (13) of two side flaps (14) of film to close the tube-shaped film at the side and a transversal welding group (15) of the tube of film between the products. The welding groups (13, 15) comprise welding surfaces (24, 30) that are intended to come into contact with the film and that are heated by electrical resistances to a welding temperature and that are supported and actuated through moving means (17, 21) for their welding movement with respect to the film. The welding surfaces with the respective electrical resistances of at least one of the welding groups (13 or 15) form a welding body (26 or 32) that is separated from the respective moving means (17 or 21) through interposition of a body (27 or 33) of thermally insulating material.
摘要:
A tube connecting apparatus capable of stably and reliably connecting tubes in which liquid is contained and sealed is provided. In a tube connecting apparatus 1, a first clamp 6 and a second clamp 7 for pressing and holding tube 8, 9 are disposed in a contact state. When the second clamp 7 is driven to separate from the first clamp 6 by a second movement mechanism, the first clamp 6 is slid on the tubes by shafts 121 supporting the first clamp 6 in a vertically movable manner and is moved from a first position P1 to a second position P2. The tubes are squeezed with pressing force being gradually increased while the tubes are slid between inclined faces 67, 77 of a first engagement portion 68 and second engagement portion 78. Residual liquid inside the tubes is excluded by squeezing operation of the first clamp 6. The tubes from which the residual liquid is excluded are cut by a cutting plate 41, the tubes are moved by first and second movement mechanisms, and then the tubes are connected.

The invention relates to a method for packing wine or a similar beverage, to products obtained using this method and to a device for carrying out the method. In particular, the invention relates to a method for packing wine or a similar beverage in a container in the form of a drinking glass (9). Said container consists of glass and is sealed with a displaceable lid (1) with very poor general oxygen permeability once sealed on the container.
摘要:
An improved plastic bag sealing apparatus (10) comprised of an improved heater (28) formed of a heating wire (62) embedded in a silicon rubber material (58, 60). The heater (28) is shaped to conform to the flat planar surface (42) of a T-bar shaped heating element (26), and clamped in place with insulators (32, 34) to provide maximum transfer of heat to the heating edge (46) formed by the web portion (44) of the T-bar. The containment of heat and transfer of maximum heat to the T-bar (26) permits a substantial improvement in thermal efficiency and a substantial reduction of power consumption. The heating edge (46) of the T-bar (26) is covered with an easily replaceable TEFLONTM coated (49) heating channel (48).
