摘要： 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.

摘要： 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.

摘要： A fiber molding system for manufacturing molded parts made from environmentally friendly, degradable fiber material using a fiber molding process is disclosed. The system includes at least one first pulp reservoir; a suction tool attached to a movement unit, which as a multi-tool comprises a plurality of suction heads, each with a three-dimensionally shaped suction head suction side adapted to a contour of the molded part to be molded, and which is designed to use at least a first partially immersing of the suction tool into the first pulp and sucking the fiber material onto the respective suction head suction sides of the suction heads using negative pressure from the first pulp to form the molded part in the suction heads; an output unit for outputting the final molded part, and a control unit adapted to carry out the method on the fiber molding system.
