Abstract
Abstract Apparatus for the electronic control of a knitting machine of the type comprising a storage device having an information store in which the information of a knitting pattern is stored in block form with every information block containing all the information for one course. The information blocks are broken down into color lines related to the particular colors being knitted, and a distributor mechanism is arranged to feed the color lines to the storage units of a working store, the storage units being associated with respective knitting systems of the knitting machine. The distributor mechanism includes a programming mechanism in the form of a selector matrix controlled by a cross-bar distributor and which determines which knitting system will receive the information for any information block selected from the storage device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
Apparatus for the electronic control of a knitting machine having knitting systems for knitting a fabric, said apparatus comprising: a storage device including an information store, in which the information of a knitting pattern can be stored in block form with every information block containing all the information for one knitted course of said fabric, and including means for producing color lines for deriving color lines from every information block, each color line containing all the information relating to a particular color or property of one of said courses; and further comprising a plurality of storage units, a distributor means for feeding the color lines derived by said color lines produced means to said plurality of storage units, the storage units being positively associated with said knitting systems and said distributor means including a programming means for feeding the color lines derived from each information block to any pre-selected number of the plurality of storage units and for feeding each color line derived from an information block to any pre-selected storage unit of said number of storage units.
Claim 2
Dependent Claim
178 words
Apparatus for the electronic control of a knitting machine having knitting systems for knitting a fabric, said apparatus comprising: a storage device including an information store, in which the information of a knitting pattern can be stored in block form with every information block containing all the information for one knitted course of said fabric, and including means for producing color lines for deriving color lines from every information block, each color line containing all the information relating to a particular color or property of one of said courses; and further comprising a plurality of storage units, a distributor means for feeding the color lines derived by said color lines produced means to said plurality of storage units, the storage units being positively associated with said knitting systems and said distributor means including a programming means for feeding the color lines derived from each information block to any pre-selected number of the plurality of storage units and for feeding each color line derived from an information block to any pre-selected storage unit of said number of storage units.
Claim 3
Dependent Claim
60 words
An apparatus according to claim 1, wherein said distributor means includes a temporary storage (53) for separately storing all color lines derived from one information block and having as many outputs (C1 - C8) as there are color lines derivable from one information block, said outputs being connected via said programming means with said storage units of said working storage.
Claim 4
Dependent Claim
94 words
An apparatus according to claim 1, wherein said programming means includes a selector matrix (77) having as many outputs as there are color lines derivable from said information blocks, each output being connected with a control input of a gating means (N1 to N8) for opening or closing said gating means, and having as many inputs as there are knitting systems, said inputs being coupled to a system stroke counter (81), and wherein each gating means has a second information input coupled to receive one of said color lines derived from every information block.
Claim 5
Dependent Claim
90 words
An apparatus according to claim 2, wherein said programming means includes a selector matrix (77) having as many outputs as there are color lines derivable from said information blocks, each output being connected with a control input of a gating means (N1 to N8) for opening and closing said gating means, and having as many inputs as there are knitting systems, said inputs being coupled to a system stroke counter (81), and wherein each gating means has a second information input coupled to an associated output of said temporary store.
Claim 6
Dependent Claim
31 words
An apparatus according to claim 3, wherein the control inputs of said gating means are coupled to a cross bar distributor means, said cross bar distributor means being said selectable matrix.
Claim 7
Dependent Claim
21 words
An apparatus according to claim 3, wherein the control inputs of said gating means are coupled to a freely programmable store.
Claim 8
Dependent Claim
38 words
An apparatus according to claim 3, wherein said gating means have an output coupled to a demultiplexer means (59), which has a plurality of outputs each output being connected with one associated storage unit of said working storage.
Claim 9
Dependent Claim
35 words
An apparatus according to claim 7, said working storage being coupled to said knitting systems and having a staggering means for bringing the information into a sequence as it is necessary for the knitting process.
