A winder unit (1) for winding cutting line (41), for vehicle glazing panel removal, has a rotatable spindle shaft (61) for winding the cutting line (41) and a ratchet device (90) mounted to the spindle shaft (61) by means of a one-way rotational bearing or clutch (75). Typically the ratchet device (90) has a component mounted to rotate in unison with the one-way rotational bearing or clutch. The improvement provides a rotational directional control providing 2 one-way rotational control devices in concert.

A deflection roller (32) for a deflection roller package (33) of a wire saw (1), having a wheel (32), a pivot bearing (42) and a sealing element (55). The wheel (32) has a raceway (45) along the periphery thereof for guiding a saw wire (3) of the wire saw (1). The pivot bearing (42) is coaxially inserted in the wheel (32). An outer sleeve (51) protrudes from a lateral surface (49) of the wheel (32). An inner sleeve (50) protrudes from a lateral surface opposite the one lateral surface (49). A radius (53) of the inner sleeve (50) is smaller than a radius (52) of the outer sleeve (51). The sealing element (55) is placed on the outer sleeve (51) or inserted into the inner sleeve (50).

Method of coiling a flexible elongate element (64) inside a container (80A) made from a flexible sheet material wherein at least part of the sheet material is tensioned by establishing a pressure differential between an inner surface (100) and an outer surface (92) of the sheet material and the flexible elongate element (64) is directed onto the tensioned sheet material to form a hole (98), the flexible elongate element being then fed through the hole to form a coil inside the container.

A coil support with a coil of a trimmer line has a coil core with an outer wall surface and first and second axial ends. At the axial ends securing elements that project past the wall surface of the coil core are provided for positional fixation of the coil wound onto the coil core. A securing element provided at the first axial end is a support plate with a longitudinal center axis. The size of the support plate is provided in the direction of the longitudinal center axis with a greater extension than transverse to the longitudinal center axis such that the support plate in a first radial direction of the coil core is greater than in a second radial direction. The coil core is fixedly connected with the support plate and with the further securing elements that are provided on the second axial end.
