Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
145 words
In a method for controlling patterning and working width in flat-bed knitting machines by means of data carriers, the steps of calling from non-erasable storage means signals representative of data for the basic kinds of knitting, for the needle setting s and for a number of edge needles and applying said signals to control corresponding operations of said machine, and at the same time transferring further signals representative of data for jacquard patternings from a further storage means, to an erasable temporary storage means, and applying signals from said temporary storage means to control jacquard patterning in said machines, positioning limit switches to predetermined locations along the knitting machine carriage, actuating said limit switches when the knitting machine carriage passes said predetermined locations and directing the outputs from said limit switches to suppress corresponding predetermined signals representative of data for the number of edge needles.
Claim 2
Dependent Claim
145 words
In a method for controlling patterning and working width in flat-bed knitting machines by means of data carriers, the steps of calling from non-erasable storage means signals representative of data for the basic kinds of knitting, for the needle setting s and for a number of edge needles and applying said signals to control corresponding operations of said machine, and at the same time transferring further signals representative of data for jacquard patternings from a further storage means, to an erasable temporary storage means, and applying signals from said temporary storage means to control jacquard patterning in said machines, positioning limit switches to predetermined locations along the knitting machine carriage, actuating said limit switches when the knitting machine carriage passes said predetermined locations and directing the outputs from said limit switches to suppress corresponding predetermined signals representative of data for the number of edge needles.
Claim 3
Dependent Claim
32 words
A method according to claim 1 wherein the signals from said erasable temporary storage means are transferred with priority over the signals called from the non-erasable storage means containing needle setting data.
Claim 4
Dependent Claim
48 words
A method according to claim 1 wherein the signals from the storage means containing data pertaining to the number of edge needles are transferred with priority over the signals called from the erasable temporary storage means and over signals called from the storage means containing needle setting data.
Claim 5
Dependent Claim
43 words
A method according to claim 1 wherein the transfer of data from selected storage means is suppressed in pre-selected areas by adjustment of the switching times of limit switches arranged to control the flow of signals from said storage means to said machine.
Claim 6
Dependent Claim
42 words
A method according to claim 1 wherein signals representative of data for controlling machine operation in a given row are transferred from said further storage means to said temporary erasable storage means during the next preceeding return of the knitting machine carriage.
Claim 7
Dependent Claim
35 words
A method according to claim 1 wherein the signals representative of data for knit types, for needle setting and for the number of edge needles are obtained optionally from fixed and from exchangeable storage means.
Claim 8
Dependent Claim
38 words
A method according to claim 1 wherein the calling and transfer of signals is executed automatically by means of control signals from storage means in the knitting machine, and optionally by the control device of said knitting machine.
Claim 9
Dependent Claim
25 words
A method according to claim 1 wherein the switching instants of limit switches for changing of working width in said knitting machine are adjusted automatically.
Claim 10
Dependent Claim
37 words
A method according to claim 1 wherein the further storage means containing signals representative of data for jacquard patternings are read repeatedly, in alternating steps and different movement directions of the storage mediums of said storage means.
Claim 11
Dependent Claim
62 words
A method according to claim 9 wherein said further storage means is controlled by the control device of the knitting machine and optionally a control tape of the further storage means itself by choice once forward, twice forward, once in reverse or twice in reverse and in that the reading of the data is effected in each of the directions of movement.
Claim 12
Dependent Claim
57 words
A method according to claim 1 wherein signals representative of data groups for several jacquard patterns are storeD on a storage medium in said further storage means, wherein between individual data groups on said machine identifying characters are stored, and wherein said identifying characters are read for selection of the data group of the desired jacquard patterning.
Claim 13
Dependent Claim
47 words
A method according to claim 1 wherein for the purpose of staggering of a pattern repetition, the reading from the erasable temporary storage means, on repitition of the calling and the transmission of data, is started at a position which is different from the preceding reading position.
Claim 14
Dependent Claim
129 words
In combination with a knitting machine control apparatus for controlling the patterning and working width of a flat-bed knitting machine having a carriage movable back and forth over a given path, nonerasable storage means for providing signals representative of data for patterning and for setting of working width, means for selectively calling for signals from said nonerasable storage means, a movable magnetic tape storage means with erasable temporary storage means and automatically actuated limit switches for setting of working width, said limit switches being adjustable mounted for movement to different locations along the carriage, said switches being operable in response to the knitting machine carriage past said locations along said path, said limit switches being connected to control outputs from said storage means for setting of said working width.
Claim 15
Dependent Claim
129 words
In combination with a knitting machine control apparatus for controlling the patterning and working width of a flat-bed knitting machine having a carriage movable back and forth over a given path, nonerasable storage means for providing signals representative of data for patterning and for setting of working width, means for selectively calling for signals from said nonerasable storage means, a movable magnetic tape storage means with erasable temporary storage means and automatically actuated limit switches for setting of working width, said limit switches being adjustable mounted for movement to different locations along the carriage, said switches being operable in response to the knitting machine carriage past said locations along said path, said limit switches being connected to control outputs from said storage means for setting of said working width.
Claim 16
Dependent Claim
56 words
In a knitting machine control apparatus according to claim 13 wherein said non-erasable storage means and said erasable temporary storage means each have outputs connected with one another by means of OR-gates, (66, 114, 116, 122; 75), AND-gates (64, 111, 118, 124; 72, 87, 82, 84) and INHIBITORY-AND-gates (65, 108, 113, 120; 151, 158, 155, 159).
