TOOL FOR HF WELDING, INSTALLATION FOR PRODUCING A BAG FOR MEDICAL PURPOSES AND METHOD FOR OPERATING SUCH AN INSTALLATION
The invention relates to various aspects of HF welding methods and HF welding devices. When welding in insert parts comprising two films extending in the same axial direction to form a bag, it is proposed that the upper tool (2) and the lower tool (3) each consist of a plurality of electrode lamellae arranged next to one another, wherein the electrode lamellae are oppositely poled alternately along the axial direction of the insert part and perpendicularly to the axial direction.

TOOL, TOOL STATION, THERMOFORMING SYSTEM AND METHOD FOR OPERATING A THERMOFORMING SYSTEM
The invention relates to a tool (2, 3) for moulding a moulded part (4) made of thermoplastic material and to a corresponding system and to a method. The invention relates to, in particular, the production of semi-finished products for refrigerators with a groove for receiving a seal. According to the invention, during demoulding from the undercut groove, a force acting upon the notches is braced and guided towards the residual film grid.
The invention relates to a transport system (1) for a group (2, 13) of identical workpieces, in particular identical plastics workpieces, said transport system (1) being constructed as a system part of a plastics-processing joining system for delivering the semi-finished products as one step in the manufacture of products. The transport system comprises a group of workpiece carriers (4, 12) on a circulating working conveyor belt, said workpiece carriers (2, 12) of the group (2, 13) having identical holding regions (15), such that a respective holding region (15) on one of the workpiece carriers of the group (2, 13) can co-operate with one of the identical workpieces. The transport system (1) is configured to simultaneously transport, during operation, a number of the identical workpieces along the working conveyor belt by means of the group (2, 13) of workpiece carriers and said transport system has a working belt discharge means and a working belt feed means for the group of workpiece carriers.
The invention relates to an installation and a method for producing infusion bags having a means of access and an injection stopper. The invention also relates to such a bag and various injection stoppers. In the system according to the prior art, a piece of flexible tube is welded into a bag, the port being plugged onto said piece of flexible tube. The port is not additionally fixed but is held in the flexible tube purely by way of tension. As a result, sealing problems can theoretically occur. By contrast, in the novel system proposed here, the port is welded directly into the bag. The flexible tube is thus dispensed with as an intermediate piece. This results in particular in the advantage that, for each bag, over 30 mm of flexible tube are saved, this not only making the installation construction more favourable but also doing away with the flexible tubes with their relatively high costs. Furthermore, the flexible tube and the port can optionally be welded in using the same welding tool. The operator of the installation can decide whether to weld in one flexible tube and one port or two flexible tubes. It is not necessary to change tools for this purpose. If the operator of the installation welds in two flexible tubes, the standard ports according to the prior art can still be placed on the flexible tubes.
The invention relates to a stacking station for a thermoforming plant, a method for producing cup-shaped products in a thermoforming plant and a thermoforming plant equipped therewith. Pressing products out of a film plant onto a further conveyor belt is known. The further conveyor belt initially transports the products onto a tipping device. After the tipping device has operated, the products are lying on their side and are transported onwards from there. The present invention proposes that the products coming from the ejector first be pre-stacked, then be tipped, and that preferably under their inherent weight, and then only to be stacked when lying on their side.
Systems, for example, for producing and filling bags for medical purposes, having a gripper system which passes the closed welding tool in the opposite direction to the machine, in order to save time as well as to engage the subsequent film web, are already known. According to the invention, the grippers can perform an additional stroke in order to produce waste-free medical bags.
