A fixed line style string trimmer head. A fixed-line string trimmer has a trimmer head that takes pre-cut line inserts. There is no wound spool of line in the trimmer head; the user instead feeds the pre-cut line in to the appropriate slots, making the trimmer easier to feed line into and troubleshoot than a bump feed system.

Stihl was founded in 1926 by Andreas Stihl, an innovator in early chainsaw production. Stihl says it is the world's best-selling brand of chainsaws and the only chainsaw manufacturer to make its own saw chains and guide bars. [4] Andreas Stihl AG is a privately held company owned by the descendants of Andreas Stihl.
The fleet angle is defined as the largest angle of the rope between the first sheave and the drum flange, relative to the centre line of the drum. With all type of drums, the rope is subject to a fleet angle which impacts on its behaviour and affects lifespan. Fleet angle should be between 0.25° and 1.25°, depending on the rope construction.
Winders have a center roll (a bobbin, spool, reel, belt-winding shell, etc.) on which the material is wound up. Often there are metal bars that travel through the center of the roll and are shaped according to their intended purpose. A circular bar facilitates greater speed, while a square bar provides a greater potential for torque.
A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. [1] Bobbins are typically found in industrial textile machinery , [ 2 ] as well as in sewing machines , fishing reels , tape measures , film rolls , cassette tapes , within electronic and electrical equipment, and for various ...
permitted the use of in-line splices in walls without a junction box (however, this downside is offset by the strong nature of the soldered and taped junctions used at the time). susceptible to mechanical damage in accessible areas; Knob-and-tube wiring at a museum display
The compressor spool, turbine and compressor, is in green. The free power turbine is in purple. A free-turbine turboshaft is a form of turboshaft or turboprop gas turbine engine where the power is extracted from the exhaust stream of a gas turbine by an independent turbine, downstream of the gas turbine. The power turbine is not mechanically ...
Backing is the rearmost section of the fishing line and typically used only to "pad up" the spool of the fishing reel, in order to prevent unwanted slippage between the mainline and the (usually metallic and well polished) spool surface, increase the effective radius of the spooled line and hence the retrieval speed (i.e. inches per turn), and ...
