Description

Arm (6) is held and can be firmer when it occurs.

A further advantage is that the one normally locked locking device position of the roller gap between the feed rollers (25,26,27) as a function of the movement rolls to any value during operation (6) to unlock, besides the glass piston blow molding machine is adjustable

It is desirable that the stream be melted while the second feed roller 3 is rotatable in glass held from the outlet opening of a melting arm 6. This moving furnace exits and in a gas piston blow molding machine arm 6 is placed on rails 5 α , which enters horizontally and has a uniform melt state 55 on the side walls of the machine frame 5. If abnormally solid components are such as solidified, and in FIG. 2 and 4, viewed according to lumps or unmelted raw material, or, on the left, with the help of a mechanism to be described later, other foreign bodies can be displaced in the molten glass bite.

If the handwheel 21 counterclockwise according to FIG. 4 twisted, while according to FIG. 3 is pulled to the right, the ring 15 clamped between the rollers 19 of the slide 28 in FIG. 2 seen to the left moved as the shaft 18 is rotated so that the movable arm 6 and the feed roller 3 over the Adjusting rod 12 can be moved to the left. After the handwheel 21 has been reset, the feed roller is also there 3 returned to their original position.

So if any unusual material that is not suitable for the glass ribbon, from the glass melting furnace flows out, the operator moves the feed rollers 2 and 3 in the manner described apart and remove the unsuitable material. Since the invention the feed roller 3 of the Feed roller 2 is just removed by the distance determined by the size of the solid components is, it is not necessary to operate a number ίο of cylinder-piston units in each case. Except-, it is possible to change the thickness of the glass ribbon or. of the nip precisely and during operation easy to adjust, depending on the type and size of the glass bulbs to be produced.
