Claims (11)

1. Device for checking the flow of air through a two-stage blowing head having a first channel of the blowing head, including a first inlet for directing air for blowing into a jar, and a second channel for a blowing head including a second inlet separate from the specified first inlet for directing cooling air the neck, while the device contains a transition unit with means for removable placement of the blowing head, and the specified transition unit has a first channel unit for supplying test air in said first inlet and said first channel of the blow head, and a second channel of the unit for supplying test air to said second inlet and said second channel of the blowing head, first means for supplying test air from the source of test air to said first channel of the unit, and second means supplying test air from the same test air source to said second channel of the unit, said first and second means comprising means for measuring the air flow, respectively to the specified first and second channels of the block.  2. The device according to claim 1, wherein said transition unit includes a glass blow head for removable placement of one end of a two-stage blow head.  3. The device according to claim 2, wherein said cup contains a holder mounted on said block, a wear-compensating plate for coupling with a blow head mounted in said cup, and a helical spring positioned in a compressed state between said bracket and said wear-compensating plate , with the specified first channel of the block and the specified second channel of the block pass through the specified block, the specified holder and the specified wear-compensating plate.  4. The device according to claim 1, wherein said means for measuring air flow to said first and second channels of the unit comprises means for measuring air pressure and air mass flow through said first and second channels of the unit separately from each other.  5. The device according to claim 4, further comprising first and second pressure regulators for regulating the pressure of the air flow, respectively, through said first and second channels of the unit.  6. The device according to claim 4, further comprising a test vessel for insertion into the blow head to simulate the back pressure of air in said first and second channels of the blow head.  7. The device according to claim 1, wherein said second means further includes means for releasably connecting the plunger cooler to check the flow of air through the plunger cooler.  8. The device according to claim 7, wherein the means for detachably attaching the plunger cooler comprises a head for the plunger in said second means between said air flow measuring means and said transition unit, and in the said head for the plunger a stopper is installed for removal to connect the plunger cooler with the specified head for the plunger. 9. A method of checking the flow of air through a two-stage blow head having a first channel of the blow head, including a first inlet for directing the blowing air into a jar, and a second channel of the blow head including a second inlet separate from the first inlet, for directing the neck cooling air, moreover, this method contains:
(a) supplying pressurized air separately to said first and second inlets of the blowing head, and
(b) measuring at this stage (a) the air flow separately to said first and second inlets. 10. The method according to p. 9, in which the specified stage (a) contains the following stages:
(a1) using an adapter for a blowing head having a first channel of the air supply unit to the first input of the blowing head and a second channel of the air supply unit to the second input of the blowing head, and
(A2) removable mounting the blow head to the specified transition unit, so that the first and second channels of the block are located in the specified mounting block.  11. The method according to claim 9, wherein said step (b) comprises the step of measuring air pressure and air mass flow rate separately to said first and second inlets.
