Document Type and Number:
Japanese Patent JPH02196684
Kind Code:
A
Abstract:
PURPOSE: To enhance the printing strength of a bonded part by adding a polyamide resin powder to ink.
CONSTITUTION: Both end parts of an ink ribbon consisting of a ribbon base material composed of a polyamide rein fiber and ink having a polyamide resin powder added thereto are overlapped and subjected to ultrasonic bonding to form an endless ink ribbon. By this method, the original fiber state of the ribbon base material can be kept and bonding strength can be increased. The bonded part of the obtained endless ink ribbon is not damaged by the impact due to a dot pin and tension at the time of the running of the ribbon.
