System and method for producing a bag for medical purposes

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.. . ...

System and method for manufacturing a bag for medical purposes

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. ...

Method for producing a thermoformed product, and installation and machine therefore

A method for producing a thermoformed product on a single machine with several stations and with different tools includes the following steps: (a) melting and homogenizing plastic granules and providing the plastic melt at a preform station; (b) producing a preform at the preform station in a preform cavity; (c) transferring the preform by a transfer carrier to a thermoforming station at the same machine, the thermoforming station having a thermoforming tool having a thermoforming cavity; (d) preferably heating the preform during the transfer; (e) thermoforming of the thermoformed product in the thermoforming cavity. Advantageously, the final thermoformed product is produced directly from the plastic granules using only a single machine, and in particular without any waste, when the preform is dimensioned in such a way that it does not present any excess with respect to the final shape of the product to be produced.. ...

Plant for manufacturing bags from two layers of plastic film, method for operating such a plant and bag

An installation for producing bags from two-layer plastic film includes a film gripper for drawing the plastic film into a tool at a first station, and a rotary conveyor belt for conveying the film through a plurality of stations. The film gripper is designed to guide the plastic film through the first station to a second station.. ... Kiefel Gmbh

Method and system for manufacturing medical pouches

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. ...
