Abstract
Abstract A device for positioning tentering frames into association with a workpiece which is being assembled along a transfer line which has a working station includes a movable guiding section which extends substantially perpendicular to the transfer line at the working station on each side of the transfer line at the working station on each side of the transfer line. The movable guiding section includes a sliding platform which is movable therealong on each side of the transfer line and which has a portion facing the assembly line with means for engaging respective tentering frames. At least two guide members or guidings are arranged on each side of the transfer line and in spaced relationship to each other so that they extend substantially parallel to the transfer line. Each guiding carries at least three tentering frames which are movable therealong into association with the platforms. The platforms are movable between working positions close to the transfer line and to a withdrawn position remote from the transfer line.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A device for positioning tentering frames into associating with a workpiece, the workpiece being assembled along a transfer line, the transfer line having a working station, comprising: a movable guiding section arranged substantially parallel to the transfer line, the guiding section being movable in a direction substantially perpendicular to the transfer line; at least one stationary guiding section arranged substantially parallel to the transfer line; at least two tentering frames each tentering frame being slidable on said movable guiding section and said stationary guiding section; a waiting position defined by said tentering frames being on one of said at least one stationary guiding section; a working position defined by one of said tentering frames being on said movable guiding section and said movable guiding section being close to said transfer line; said movable guiding section being alignable with each of said at least one stationary guiding section defining at least one aligning position; each of said tentering frames being slidable from said movable guiding section to said stationary guiding section and from said stationary guiding section to said movable guiding section in said at least one aligning position.
Claim 2
Independent Claim
188 words
A device for positioning tentering frames into associating with a workpiece, the workpiece being assembled along a transfer line, the transfer line having a working station, comprising: a movable guiding section arranged substantially parallel to the transfer line, the guiding section being movable in a direction substantially perpendicular to the transfer line; at least one stationary guiding section arranged substantially parallel to the transfer line; at least two tentering frames each tentering frame being slidable on said movable guiding section and said stationary guiding section; a waiting position defined by said tentering frames being on one of said at least one stationary guiding section; a working position defined by one of said tentering frames being on said movable guiding section and said movable guiding section being close to said transfer line; said movable guiding section being alignable with each of said at least one stationary guiding section defining at least one aligning position; each of said tentering frames being slidable from said movable guiding section to said stationary guiding section and from said stationary guiding section to said movable guiding section in said at least one aligning position.
Claim 3
Dependent Claim
26 words
A device according to claim 1, wherein said movable guiding section can be positioned in an intermediate position between said working position and said waiting position.
Claim 4
Dependent Claim
17 words
A device according to claim 1, wherein said movable guiding section is mounted on a movable platform.
Claim 5
Dependent Claim
16 words
A device according to claim 3, wherein the movable guiding section is formed as a gantry.
Claim 6
Dependent Claim
41 words
A device according to claim 10, wherein said gantry includes at least two vertical guiding pillars disposed on the edge of said movable platform toward the transfer line, at least two guiding elements being arranged on each of said guiding pillars.
Claim 7
Dependent Claim
21 words
A device according to claim 3, further comprising at least one industry robot mounted on said platform for treating the workpiece.
Claim 8
Dependent Claim
29 words
A device according to claim 1, wherein said tentering frames include narrow sides having coupling parts which can interengage each other thereby effecting corresponding movements of said tentering frames.
Claim 9
Independent Claim
205 words
A device for positioning tentering frames into association with a workpiece which is assembled along a transfer line which has a working station, comprising: a movable guiding section arranged substantially parallel to the transfer line, and being movable in a direction substantially perpendicular to the transfer line; at least one stationery guiding section arranged substantially parallel to the transfer line; at least two tentering frames each beng slidable on said movable guiding section and said stationary guiding section; a waiting position defined by said tentering frames being on one of said at least one stationary guiding section; a working position defined by one of said tentering frames being on said movable guiding section and said movable guiding section being close to said transfer line; said movable guiding section being alignable with each of said at least one stationary guiding section defining at least one aligning position; each of said tentering frames being slidable from said movable guiding section to said stationary guiding section and from said stationary guiding section to said movable guiding section in said at least one aligning position; each of said tentering frames having coupling parts, said coupling parts being interengageable with each other, thereby effecting corresponding movements of said tentering frames.
Claim 10
Independent Claim
205 words
A device for positioning tentering frames into association with a workpiece which is assembled along a transfer line which has a working station, comprising: a movable guiding section arranged substantially parallel to the transfer line, and being movable in a direction substantially perpendicular to the transfer line; at least one stationery guiding section arranged substantially parallel to the transfer line; at least two tentering frames each beng slidable on said movable guiding section and said stationary guiding section; a waiting position defined by said tentering frames being on one of said at least one stationary guiding section; a working position defined by one of said tentering frames being on said movable guiding section and said movable guiding section being close to said transfer line; said movable guiding section being alignable with each of said at least one stationary guiding section defining at least one aligning position; each of said tentering frames being slidable from said movable guiding section to said stationary guiding section and from said stationary guiding section to said movable guiding section in said at least one aligning position; each of said tentering frames having coupling parts, said coupling parts being interengageable with each other, thereby effecting corresponding movements of said tentering frames.
