Title:
プレスベルト溝構造
Document Type and Number:
Japanese Patent JP3749256
Kind Code:
B2
Abstract:
The grooves of a grooved press belt are formed with an improved configuration which reduces groove closure under pressure and which reduces cracking and tearing of the belt. The improved groove configuration consists of a curved bottom and two upwardly diverging side walls. In a first embodiment the bottom wall is semi-circular and has a diameter which is equal to about one half of the width of the groove opening. The upwardly diverging side walls preferably include radiused upper edges. The side walls preferably have an angle of divergence between about five degrees and about fifteen degrees from a vertical plane. In a second embodiment, the bottom of the groove is substantially flat, and the bottom corners are radiused to provide a smooth transition between the flat bottom and the upwardly diverging side walls.
