Abstract

The apparatus is for simultaneously fabricating plastic bags and completely filling them with a mixture of different materials. At the same time, the apparatus insures that the contents of one primary bag do not contaminate the contents of the succeeding primary bag. The bags thus formed are particularly useful for processing blood samples through a colorimeter.

Bag Fabricating and Filling Machine

The apparatus is for simultaneously fabricating plastic bags and completely filling them with a mixture of different materials. At the same time, the apparatus insures that the contents of one primary bag do not contaminate the contents of the succeeding primary bag. The bags thus formed are particularly useful for processing blood samples through a colorimeter.

The upper drawing is a front view, partially sectioned, of the essential components of the apparatus. This basically comprises two identical, opposed wheels 1 and 2 mounted for opposite rotation. Both wheels 1 and 2 have complementary cavities 21...30 spaced serially around the peripheries. The peripheral edges of opposed cavities, which are in rolling contact at a point fixed on a line connecting the wheel centers and equidistant from it, are heated. Thermosetting ribbons 13 pass between the wheels and are drawn into contact with the cavity walls. Such is effected by a vacuum created in the respective ports communicating with each cavity. The opposing cavity edges bond corresponding portions of each ribbon forming the bags.

Bonding actually occurs at the fixed point where complementary edge portions of the cavity meet. Concurrently with the fabrication of the larger size or primary bags, the material to be placed in the primary bags is released from distribution tubes 15. The material is then mixed by ultrasonically modulating the vacuum. As wheels 1 and 2 continue to...
