Abstract
A machine for laying down and taking up strips of artificial turf comprising a self-powered, highly maneuverable carrier having means for transporting, picking up and winding or unwinding a roll of turf strip. Means are provided to shift the roll axially relative to the carrier to precisely lay down each strip in side-by-side relation with a previously laid strip.
Claims15
Apparatus for handling a strip of artificial turf or the like comprising
- a wheeled carrier,
- means for driving said carrier over the ground,
- spaced support members on said carrier for supporting the opposite ends of a mandrel on which a roll of said strip is to be wound or unwound,
- means for raising or lowering said support members relative to said carrier whereby to raise or lower said roll,
- a roller carried by said carrier for frictionally engaging the periphery of said roll, and
- drive means on said carrier for rotating said roller whereby to wind said strip.
