Abstract
Abstract A continuous or ring-shaped printing ribbon is constructed by overlapping the ends of a length of ribbon made of thermoplastic synthetic material and welding the overlapped ends together along a grid work of fine weld lines, thereby providing a weld joint comprising a punctiform arrangement of ink-bearing cells to effect an undisturbed emission of ink across the joint during a printing operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
68 words
In a ring-shaped ribbon made of thermoplastic material having at least one color track and formed from a strip of the ribbon of finite length, the end portions of which are overlapped and fused to form a continuous ribbon, the improvement wherein the overlapped end portions of the ribbon strip are welded in grid form to provide a series of spaced welded line joints having ink-bearing cells therebetween.
Claim 2
Dependent Claim
68 words
In a ring-shaped ribbon made of thermoplastic material having at least one color track and formed from a strip of the ribbon of finite length, the end portions of which are overlapped and fused to form a continuous ribbon, the improvement wherein the overlapped end portions of the ribbon strip are welded in grid form to provide a series of spaced welded line joints having ink-bearing cells therebetween.
Claim 3
Dependent Claim
17 words
The invention as defined in claim 1 in which said ribbon comprises more than one color track.
Claim 4
Dependent Claim
68 words
In the method of making a ring-shaped thermoplastic ribbon having at least one color track, by overlapping the end portions of a strip of the ribbon of finite length and fusing said end portions to form a continuous ribbon, the improvement wherein said end portions are fused by welding same under conditions of pressure and temperature in a grid form to retain ink-saturated cells within said end portions.
Claim 5
Dependent Claim
68 words
In the method of making a ring-shaped thermoplastic ribbon having at least one color track, by overlapping the end portions of a strip of the ribbon of finite length and fusing said end portions to form a continuous ribbon, the improvement wherein said end portions are fused by welding same under conditions of pressure and temperature in a grid form to retain ink-saturated cells within said end portions.
Claim 6
Dependent Claim
19 words
The invention as defined in claim 3 in which said overlapping end portions are ultrasonically welded to one another.
Claim 7
Dependent Claim
52 words
The invention as defined in claim 4 wherein said ultrasonic welding comprises the steps of disposing the overlapped end portions of the ribbon between a pair of metal wire meshes, and positioning the sonotrode of an ultrasonic welding device in relation to one of said wire meshes to oscillate into engagement therewith.
Claim 8
Dependent Claim
43 words
A sonotrode for use in ultrasonic welding device for welding the overlapping end portions of a strip of ribbon to form a continuous ribbon comprising a working surface, and prominences formed on said working surface and arranged in the manner of a grid.
Claim 9
Dependent Claim
43 words
A sonotrode for use in ultrasonic welding device for welding the overlapping end portions of a strip of ribbon to form a continuous ribbon comprising a working surface, and prominences formed on said working surface and arranged in the manner of a grid.
