Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 143 words
A textile machine comprising in combination: a processing element, said processing element having a working shape, said working shape having a predominant influence on at least one quality parameter of a product being produced on said machine; the working shape of said processing element deteriorating as an operating period of said machine increases, with product quality of said product being impaired accordingly; a built-in maintenance element, operatively associated with said processing element, said maintenance element improving the working shape of said processing element by treatment thereof in order to counteract the impairment of the quality of said product; said maintenance element being movable between a waiting position and an operating position; and a control unit, operatively interconnected with said maintenance element, said control unit controlling or initiating the movement of said maintenance element from said waiting position to said operating position and vice-versa.
Claim 2
Dependent Claim 143 words
A textile machine comprising in combination: a processing element, said processing element having a working shape, said working shape having a predominant influence on at least one quality parameter of a product being produced on said machine; the working shape of said processing element deteriorating as an operating period of said machine increases, with product quality of said product being impaired accordingly; a built-in maintenance element, operatively associated with said processing element, said maintenance element improving the working shape of said processing element by treatment thereof in order to counteract the impairment of the quality of said product; said maintenance element being movable between a waiting position and an operating position; and a control unit, operatively interconnected with said maintenance element, said control unit controlling or initiating the movement of said maintenance element from said waiting position to said operating position and vice-versa.
Claim 3
Dependent Claim 48 words
The textile machine of claim 1, wherein said control unit is provided with a program which affects the movement of said maintenance element to one of said operating position and the return movement to said waiting position in accordance with a work cycle as defined by said program.
Claim 4
Dependent Claim 20 words
The textile machine of claim 2, wherein said work cycle includes a predetermined time interval (t) between successive operating cycles.
Claim 5
Dependent Claim 13 words
The textile machine of claim 3, wherein said time interval (t) is adjustable.
Claim 6
Dependent Claim 35 words
The textile machine of claim 1, includes a sensor, said sensor being operatively interconnected with said control unit, said sensor responding to the said at least one quality parameter and generating a respective output signal.
Claim 7
Dependent Claim 34 words
The textile machine of claim 1, including a sensor, said sensor being operatively interconnected with said processing element, said sensor responding to the condition of said processing element and generating a respective output signal.
Claim 8
Dependent Claim 44 words
The textile machine of claim 5, wherein the output signal of said sensor is supplied to said control unit and the movement of said maintenance element from said waiting position to said operating position is initiated depending on the output signal of said sensor.
Claim 9
Dependent Claim 44 words
The textile machine of claim 6, wherein the output signal of said sensor is supplied to said control unit and the movement of said maintenance element from said waiting position to said operating position is initiated depending on the output signal of said sensor.
Claim 10
Dependent Claim 16 words
The textile machine of claim 7, wherein the signal level which initiates said movement is adjustable.
Claim 11
Dependent Claim 16 words
The textile machine of claim 8, wherein the signal level which initiates said movement is adjustable.
Claim 12
Dependent Claim 47 words
The textile machine of claim 1, wherein said processing element extends over a specific processing width; said maintenance element extends only over a part of said processing width and an operating cycle of said maintenance element comprises at least one stroke movement over said whole processing width.
Claim 13
Dependent Claim 15 words
The textile machine as claim 11, wherein the speed of said stroke movement is adjustable.
Claim 14
Dependent Claim 31 words
The textile machine of claim 11, wherein said control unit is provided with a program which determines the number of stroke movements over the whole processing width during every processing cycle.
Claim 15
Dependent Claim 31 words
The textile machine of claim 12, wherein said control unit is provided with a program which determines the number of stroke movements over the whole processing width during every processing cycle.
Claim 16
Dependent Claim 17 words
The textile machine of claim 14, wherein the number of stroke movements per processing cycle is adjustable.
Claim 17
Dependent Claim 30 words
The textile machine of claim 15, wherein the number of stroke movements per processing cycle is set by said control unit depending on an operating period of said processing element.
Claim 18
Dependent Claim 29 words
The textile machine of claim 15, wherein the number of stroke movements per operating cycle is controlled depending on the duration of a time interval between successive operating cycles.
Claim 19
Dependent Claim 29 words
The textile machine of claim 4 wherein the number of stroke movements per operating cycle is controlled depending on the duration of the time interval between successive operating cycles.
Claim 20
Dependent Claim 29 words
The textile machine of claim 5, wherein the number of stroke movements per operating cycle is controlled depending on the duration of the time interval between successive operating cycles.
Claim 21
Dependent Claim 29 words
The textile machine of claim 6, wherein the number of stroke movements per operating cycle is controlled depending on the duration of the time interval between successive operating cycles.
Claim 22
Dependent Claim 39 words
