摘要： The invention is directed to a cutterhead for attachment to a vegetation cutting apparatus. The cutterhead has a housing with a spool on which a coil of cutting filament is wound. The cutting filament is paid out in incremental lengths when its ends effective for cutting are worn. This is achieved with an incremental rotation of the spool while the cutterhead rotates. For this purpose, the filament coil must have a winding rotation corresponding to the direction of rotation of the cutterhead. So that the cutterhead can be utilized for oppositely directed rotations as desired, the spool can be turned over through 180.degree. and can be blocked and released in both positions by means of a switching member to provide the incremental rotation. The spool can be seated on the switching member and its position, when installed, is determined by means of a marking which is applied to the adapter nut and to the spool. The adapter nut serves to tighten the cutterhead onto the vegetation cutting apparatus.

摘要： The cutterhead includes a cutting filament wound on a spool and this cutting filament is adjusted with respect to its effective cutting length in dependence upon the rotational speed of the cutterhead. The switching point for the automatic feed must be precisely matched to the drive speed in order that the desired effective cutting length is maintained. In order to assure the desired effective cutting length, a spring is provided which is adjustable with respect to its biasing force by means of an easily accessible adjusting member. This biasing force is matched to the speed-dependent centrifugal force such that the spool is released at a predetermined speed of the cutterhead.

摘要： A brushcutter has a supporting tube having a first end and a second end with a drive motor arranged at the first end and a cutterhead mounted on the second end. A handle is mounted on the supporting tube for manipulating the brushcutter. The handle has a tubular-shaped handle portion which can be attached to the supporting tube without first disassembling the latter from the motor or the cutterhead. This is achieved configuring the tubular-shaped handle portion to be made of two clamshells which conjointly define a partition plane in the direction of the longitudinal axis of the supporting tube. One of the clamshells holds all control components and is directly mounted on the supporting tube by means of a pipe clamp. The other clamshell is laterally attached to the first clamshell.

摘要： The invention is directed to a threaded closure for a fuel tank and includes a thread formed on a fuel inlet stub of the tank. A closure cap has a thread for engaging the thread on the inlet stub. A latch member is arranged on the closure cap and includes a peripheral ring which is mounted on the base body of the closure cap so as to be axially journalled thereon for movement between an unlatched position whereat a handle of the peripheral ring projects beyond the upper surface of the base body to facilitate manually grasping the closure cap and for providing a visual indication that the latch member is in the unlatched position. The peripheral ring includes a toothing formed on the inner wall surface thereof for engaging the toothing formed on the outer wall surface of the inlet stub when the latch member is in the latched position thereby preventing an unintended rotation of the closure cap. Also, in the latched position, the handle is recessed in a recess formed in the base body of the cap.

摘要： A cutterhead is disclosed for a motor-driven vegetation cutter and has a rotating housing and a spool journalled therein on which a cutting filament is wound. The spool has a plurality of cams, which coact with at least two spring-loaded coupling members pivotally mounted on the housing for paying out the cutting filament in incremental lengths. Each of the coupling members is pivotally journalled on its own pivot mount on the housing such that it is pivotable in dependence upon centrifugal force. The pivotable coupling members are synchronously displaceable and are coupled to one another for this purpose via an intermediate ring which is supported on the housing so as to be freely rotatable with respect thereto.
