In order significantly to reduce the risk of contamination of a bag for medical purposes, in particular due to residual particles of tube material caused during cutting of a tube for access to the bag, the invention proposes a system (1) for producing a bag for medical purposes, comprising a tube transfer station (2) with a transfer means (3) for transferring a tube (11) coming into the tube transfer station (2) to a holder (10) and for the severing there of a tube section (17) transferred to the holder (10) from a remaining portion (18) of the incoming tube (11) in order subsequently to be able to make the severed tube section (17) connectable to two film layers for forming an access to the bag, wherein the tube transfer station (2) has a tube-tension-holding means (15) on the holder side and also a tube-pulling means (16), which means are designed to introduce tensile forces (19) between the severed tube section (17) and the remaining portion (18) of the incoming tube (11) while the severing takes place.

The aim of the invention is to avoid the risk of contamination of a bag for medical purposes, in particular to significantly reduce the amount of residual particles of material during the cutting of a tube for access to the bag. The invention proposes a system (1) for producing a bag for medical purposes comprising a tube transfer station (2) having transfer means (3) for transferring a tube (11), which is being transported towards the tube transfer station (2), to a holder (10) and for separating there a tube section (17) transferred to the holder (10) from a remainder (18) of the tube (11), in order to then render the separated tube section (17) connectible to two film layers to form an access to the bag. The tube transfer station (2) comprises at least one air nozzle (55, 57), and an effective area (58) of the at least one air nozzle (55, 57) is directed onto a designated location (20) for separation such that a forced air flow (56) in the designated location (20) forced by air blown out and/or drawn in can be adjusted for separation.

The invention relates to a system for manufacturing medical pouches and a method for manufacturing medical pouches in a system, said pouch being made from two layers of plastic film and at least one component per pouch, the system comprising a group of positioning aids for the components as well as a group of supports for the positioning aids, the positioning aids being supported on the supports which are conveyed in an endless path with the aid of a guiding mechanism, the system further comprising a component application station designed to bring a component, which has been introduced into the station by a positioning aid with the aid of a support, into a joining connection with the plastic film. The invention is characterized in that on the endless path, the supports are alternately guided first along a process run and then along a return run; the supports are placed at a certain distance from one another in the process run, are accelerated to increase the distance therebetween when the supports travel along the return run, and are decelerated to reduce the distance therebetween again when the supports intermittently travel along the process run. As a result, the system requires fewer product-specific parts.

A system for the production of a medical product, above all in the form of an ostomy bag, as well as a method for operation of such a system, uses a highly flexible modular system concept, in which individual feed lines for semi-finished products are provided. The feed lines can transfer semi-finished products to a main line in pre-assembled manner. In the main line, ultimate processing of the semi-finished products to produce the finished product or a further semi-finished product takes place, with the greatest possible work precision, in contrast to conventional systems that guide different film systems in different planes at a distance from one another, to allow pre-processing steps, before bringing the films together in one plane and welded to one another.
The invention relates to a stacking station for a thermoforming installation, to a method for producing cup-shaped products in a thermoforming installation and to a thermoforming installation equipped therewith. Ejecting products out of a film plane onto an additional conveyor belt using a pusher is known. The additional conveyor belt first brings the products to a tilting device. After actuation of the tilting device, the products lie on their side and are conveyed onward from there. The present invention provides first pre-stacking the products coming from the ejector, to then tilt them, preferably by way of their own weight, and to stack them only once they are lying.
In a process of welding pieces of tubing into films with a central electrode the central electrode is divided to facilitate the welding in a single process. In the case of tools with or without a central electrode, electrode lamellae lying next to one another have a free visual connection between edges lying towards the insert piece to obtain a tight welded joint.
The invention relates to thermoforming plant and their transport chains. Various aspects of the chain and chain rails are proposed. Overall the chain operates such that less wear occurs; it can also be cooled symmetrically and the film can be better heated up to the edges.

An overload protector has an input element, an output element juxtaposed with the input element, and a clamping plate. Fasteners fix the clamping plate to one of the elements against relative movement. A coupling between the clamping plate and the other of the elements permits only limited relative movement of the elements through a stroke having a predetermined length in a predetermined direction. A connector between the clamping plate and the other element fixes the clamping plate and the other element together against relative movement until an overload force greater than a predetermined critical limit is exerted shifting either of the elements toward or away from the other element in the predetermined direction.
