Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
110 words
In a plant for producing enameled wire using an inline process for processing wire coming from a wire pay-off system, having in order, a wire drawer, a bare wire annealer, an enamel dope coater, an enamel processing unit and an enameled wire take-up unit, wherein the improvement comprises the plant having a common oven housing within which the bare wire annealer and the enamel processing unit are placed as single processing stage, a retort, structures having within them a drying space and jointed thereto a curing space, a return shaft and a blower for blowing hot air current in a single circuit in counter current with respect to said wire.
Claim 2
Dependent Claim
110 words
In a plant for producing enameled wire using an inline process for processing wire coming from a wire pay-off system, having in order, a wire drawer, a bare wire annealer, an enamel dope coater, an enamel processing unit and an enameled wire take-up unit, wherein the improvement comprises the plant having a common oven housing within which the bare wire annealer and the enamel processing unit are placed as single processing stage, a retort, structures having within them a drying space and jointed thereto a curing space, a return shaft and a blower for blowing hot air current in a single circuit in counter current with respect to said wire.
Claim 3
Dependent Claim
16 words
The plant as claimed in claim 1 wherein said annealer is positioned within said return shaft.
Claim 4
Dependent Claim
40 words
The plant as claimed in claim 1 having at a downstream end of said return shaft an outlet connection pipe with a waste gas pipe joined with said housing, the waste gas pipe being placed round part of the annealer.
Claim 5
Dependent Claim
43 words
The plant as claimed in claim 3 wherein in the return shaft the plant has at least one annealing tube running through the shaft lengthways and through the waste gas pipe, and a system for guiding drawn bare wire through said annealing tube.
Claim 6
Dependent Claim
38 words
The plant as claimed in claim 1 having in the curing space of the oven housing a sleeve, made of sheet metal with openings, the sleeve having inwardly running labyrinth-like plates, through which the coated wire is moved.
Claim 7
Dependent Claim
44 words
The plant as claimed in claim 5 in which the sleeve is placed at a mixing point between air circulated within the plant and air taken from the outside atmosphere, that is to say more specially between the curing space and a wire outlet.
Claim 8
Dependent Claim
64 words
The plant as claimed in claim 6 having a wire cooler placed next to the wire outlet from the oven housing, and furthermore an aspiration blower as part of the wire cooler, such aspiration blower being responsible for producing a differential pressure in the wire cooler so that a controlled excess of air may be forced into the oven housing at the wire outlet.
Claim 9
Dependent Claim
18 words
The plant as claimed in claim 7 wherein the wire cooler is joined up directly with the sleeve.
Claim 10
Dependent Claim
36 words
The plant as claimed in claim 8 characterized in that at the wire outlet at the wire cooler connection there is a heat exchanger for pre-heating air under pressure making its way into the oven housing.
Claim 11
Dependent Claim
41 words
The plant as claimed in claim 3 having a steam producer, heated by the waste gas pipe, and a steam pipe of the steam producer, such steam pipe being joined up with the annealing pipe for letting steam into the same.
Claim 12
Dependent Claim
22 words
The plant as claimed in claim 3 having in the waste gas pipe a catalyst for burning off any solvent still present.
Claim 13
Dependent Claim
25 words
The plant as claimed in claim 1 wherein the dope coater is placed within a box for clearing solvent vapors produced by the dope coater.
Claim 14
Dependent Claim
37 words
The plant as claimed in claim 1 having an air controller with which air inlet and outlet paths of the common oven housing are controlled for keeping to an unchanging level of the drying and curing temperatures.
Claim 15
Dependent Claim
19 words
The plant as claimed in claim 13 wherein the air controller takes the form of a mechanically moved door.
Claim 16
Dependent Claim
20 words
The plant as claimed in claim 13 or claim 14 having temperature feelers for temperature controlled operation of the door.
Claim 17
Dependent Claim
19 words
The plant as claimed in claim 15 wherein the temperature feelers are placed in the drying and curing zone.
Claim 18
Dependent Claim
17 words
The plant as claimed in claim 15 wherein the temperature feelers take the form of thermoelectric elements.
