Abstract
Disclosed are a cathode-ray tube dividing apparatus and a cathode-ray tube dividing method intended to simply and stably divide a cathode-ray tube in a shortened time. The dividing apparatus includes a positioning means for fixedly positioning the used cathode-ray tube at a specific location, and a cathode-ray tube heating means which is brought into contact with a specific portion on side surfaces of the cathode-ray tube for linearly heating the specific portions. The cathode-ray tube heating means includes linear heating members for imparting thermal strain to the side surfaces of the cathode-ray tube upon receiving a power, thereby dividing the cathode-ray tube into the panel portion and the funnel portion, and a power supply for supplying a heating power to the linear heating members. The power supply is adapted to supply a first power for generating cracks on the side surfaces of the cathode-ray tube to the linear heating members, and to supply, after generation of the cracks, a second power larger than the first power to the linear heating members.
