EXPANDABLE ARTIFICIAL TURF AND EXPANDING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an artificial turf which is contrived to enhance friction reduction by changing the friction properties of the artificial itself and its expansion method. ;SOLUTION: There are provided a core shaft 10 which is laid out in an underground housing pit 3 provided in a corner of a field and winds up and supports an artificial turf 12, a take-up device 7 which supports turnably the core shaft 10 and a tugging winch 5 which expands the artificial turf 12 on the field by pulling the tip of the artificial turf 12 on a turf employed for an artificial turf expansion device. Then, a fluorine plastic film 15, which is a low friction member to reduce the friction with the field, is lined on the rear surface of the artificial turf 12.;COPYRIGHT: (C)1998,JPO
