Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A weaving control for a multi-harness loom comprising drive means for each harness and electronic control means for operating the drive means to move each harness for creation of a shed pattern from warp yarns, wherein the warp yarns of the loom are divided into a number of groups of yarns equal to the number of harnesses, each harness controls one yarn from each group and means for manually selecting a pattern from a series of predefined shed patterns as the weaving process progresses, said electronic control means being responsive to said manual selection means for controlling said drive means to implement the selected pattern.
Claim 2
Dependent Claim
105 words
A weaving control for a multi-harness loom comprising drive means for each harness and electronic control means for operating the drive means to move each harness for creation of a shed pattern from warp yarns, wherein the warp yarns of the loom are divided into a number of groups of yarns equal to the number of harnesses, each harness controls one yarn from each group and means for manually selecting a pattern from a series of predefined shed patterns as the weaving process progresses, said electronic control means being responsive to said manual selection means for controlling said drive means to implement the selected pattern.
Claim 3
Dependent Claim
78 words
A weaving control system for a multi-harness loom for weaving fabrics having artistic patterns comprising drive means for each harness and electronic control means for operating the drive means to move each harness for creation of desired shed patterns means for manually selecting a pattern from a series of predefined shed patterns as the weaving process progresses, said electronic control means being responsive to said manual selection means for controlling said drive means to implement the selected pattern.
Claim 4
Dependent Claim
78 words
A weaving control system for a multi-harness loom for weaving fabrics having artistic patterns comprising drive means for each harness and electronic control means for operating the drive means to move each harness for creation of desired shed patterns means for manually selecting a pattern from a series of predefined shed patterns as the weaving process progresses, said electronic control means being responsive to said manual selection means for controlling said drive means to implement the selected pattern.
Claim 5
Dependent Claim
65 words
A control system according to claim 2, wherein the electronic control means includes computing means for storing in a memory at least two series of predefined shed patterns, each of said series of shed patterns when performed sequentially constituting a desired weave pattern, said computing means being programmed to enable a loom operator to execute manually selected predefined shed patterns from a desired weave pattern.
Claim 6
Dependent Claim
44 words
A control system according to claim 3, wherein the computing means is programmed to enable a loom operator to manually select a desired weave pattern and to then execute manually and in a sequential manner successive predefined shed patterns in the desired weave pattern.
Claim 7
Dependent Claim
42 words
A control system according to claim 4, wherein the computing means is programmed to enable the operator to execute the successive predetermined shed patterns in either an ascending or descending order from a preselected predefined shed pattern in the desired weave pattern.
Claim 8
Dependent Claim
45 words
A control system according to claim 5, wherein the computing means is programmed to memorise the last predefined shed pattern executed in a given weave pattern, said last executed predefined shed pattern constituting said preselected predefined shed pattern when the desired weave pattern is selected.
Claim 9
Dependent Claim
49 words
A control system according to claim 6, wherein the computing means is operated via a pair of manually operable switches, one switch being used to select a desired type of command and the second switch being used to provide information to execute the command selected by the first switch.
Claim 10
Dependent Claim
33 words
A control system according to claim 7, wherein the first switch for selecting the command is operable to select a desired operational function by optionally sequencing through a series of predefined operational functions.
Claim 11
Dependent Claim
23 words
A control system according to claim 8, wherein the computing means is programmed to select a predetermined operational function as a default function.
