Abstract
Abstract There are provided an improved product (1) consisting of an elongated non-metallic sheet (3) having a metal embedded therein or attached thereon over the entire length thereof and method and apparatus for producing the same. In the improved product, the sheet (13) is trimmed on each of the longitudinal sides along a line (20) a predetermined lateral distance outwardly or inwardly from the outline of the periphery (2A) of the corresponding side of the metal (2). In a case of the wire in a zigzag fashion, the wire has turning ends and the outline connects neighbouring turning ends.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
50 words
An elongated nonmetallic sheet having a metal embedded therein or attached thereon over the entire length thereof, said sheet being trimmed on each of the longitudinal sides along a line a predetermined lateral distance outwardly or inwardly from the outline of the periphery of the corresponding side of said metal.
Claim 2
Dependent Claim
50 words
An elongated nonmetallic sheet having a metal embedded therein or attached thereon over the entire length thereof, said sheet being trimmed on each of the longitudinal sides along a line a predetermined lateral distance outwardly or inwardly from the outline of the periphery of the corresponding side of said metal.
Claim 3
Dependent Claim
40 words
An elongated nonmetallic sheet having a metal as claimed in claim 1, wherein said metal is a wire arranged in a zigzag fashion and having turning ends on each longitudinal side of said sheet, the outline connecting neighboring turning ends.
Claim 4
Dependent Claim
33 words
An elongated nonmetallic sheet having a metal as claimed in claim 2, wherein said sheet comprises upper and lower heat-shrinkable layers fused together with an electric conductor, forming said zigzag wire, sandwiched therebetween.
Claim 5
Dependent Claim
33 words
An elongated nonmetallic sheet having a metal as claimed in claim 1, wherein said metal is a plate and said sheet comprises a synthetic resin plate with said metal plate being attached thereon.
Claim 6
Independent Claim
183 words
A method of trimming an elongated nonmetallic sheet having a metal embedded therein or attached thereon over the entire length thereof, comprising the steps of: applying a cutting device for cutting the sheet, said cutting device being stationary in the longitudinal direction of the sheet; transferring the sheet in the longitudinal direction along a predetermined straight transfer passage; profiling the periphery of each of the longitudinal sides of the metal gradually while the sheet is being transferred and obtaining a first information signal indicative of a position a predetermined lateral distance outwardly or inwardly from the periphery of the profile or outline; detecting the longitudinal moving distance of the sheet and obtaining a second information signal indicative of the moving distance of the sheet; and controlling the lateral movement of said cutting device in response to said first and second information signals so that the sheet is cut continuously on each of the longitudinal sides of the sheet along a line parallel to and a predetermined distance outwardly or inwardly from the periphery of the outline of the corresponding side of the metal.
Claim 7
Independent Claim
183 words
A method of trimming an elongated nonmetallic sheet having a metal embedded therein or attached thereon over the entire length thereof, comprising the steps of: applying a cutting device for cutting the sheet, said cutting device being stationary in the longitudinal direction of the sheet; transferring the sheet in the longitudinal direction along a predetermined straight transfer passage; profiling the periphery of each of the longitudinal sides of the metal gradually while the sheet is being transferred and obtaining a first information signal indicative of a position a predetermined lateral distance outwardly or inwardly from the periphery of the profile or outline; detecting the longitudinal moving distance of the sheet and obtaining a second information signal indicative of the moving distance of the sheet; and controlling the lateral movement of said cutting device in response to said first and second information signals so that the sheet is cut continuously on each of the longitudinal sides of the sheet along a line parallel to and a predetermined distance outwardly or inwardly from the periphery of the outline of the corresponding side of the metal.
Claim 8
Dependent Claim
139 words
A method as claimed in claim 5, wherein the metal is a wire arranged in a zigzag fashion and having turning ends on each longitudinal side of the sheet, and the manner is which the periphery of the sheet is profiled is such that the positions of at least three neighboring turning ends are detected and information signals indicative of the three positions are obtained, the three signals are synthesized to thereby produce a signal component displaying a part of said line parallel to said periphery of the outline and a predetermined distance outwardly from the periphery and then like signals indicative of the position of the fourth turning end and the positions of the adjoining two of said three turning ends behind the former are synthesized to produce a signal component displaying a following part of said line.
Claim 9
Independent Claim
236 words
An apparatus for trimming an elongated nonmetallic sheet having a metal embedded therein or attached thereon, comprising: a transfer device including an assembly of a plurality of tables of equal size and adapted so as to carry the sheet in the longitudinal direction along a moving passage of said transfer device; a couple of penetrant-type sensors arranged midwayfn the moving passage of said transfer device, each of said sensors being capable of profiling the periphery of each of the longitudinal sides of the metal and of generating an information signal indicative of the position of the periphery; a cutting device arranged adjacent to said sensors and being capable of moving in the lateral direction with respect to the metal and the sheet; a detecting device adapted so as to detect the moving distance of said transfer device and being capable of generating an information signal indicative of the moving distance of said transfer device; and a signal-processing system including a first signal processor for said sensors, a pulse control section for said detecting device, and a first signal processor and a second signal processor for controlling the lateral movement of said cutting device with respect to the metal and the sheet; whereby the sheet is cut automatically and continuously on each of the longitudinal sides thereof along a line a predetermined lateral distance outwardly or inwardly from the periphery of the corresponding side of the metal.
Claim 10
Independent Claim
236 words
An apparatus for trimming an elongated nonmetallic sheet having a metal embedded therein or attached thereon, comprising: a transfer device including an assembly of a plurality of tables of equal size and adapted so as to carry the sheet in the longitudinal direction along a moving passage of said transfer device; a couple of penetrant-type sensors arranged midwayfn the moving passage of said transfer device, each of said sensors being capable of profiling the periphery of each of the longitudinal sides of the metal and of generating an information signal indicative of the position of the periphery; a cutting device arranged adjacent to said sensors and being capable of moving in the lateral direction with respect to the metal and the sheet; a detecting device adapted so as to detect the moving distance of said transfer device and being capable of generating an information signal indicative of the moving distance of said transfer device; and a signal-processing system including a first signal processor for said sensors, a pulse control section for said detecting device, and a first signal processor and a second signal processor for controlling the lateral movement of said cutting device with respect to the metal and the sheet; whereby the sheet is cut automatically and continuously on each of the longitudinal sides thereof along a line a predetermined lateral distance outwardly or inwardly from the periphery of the corresponding side of the metal.
Claim 11
Dependent Claim
