Claim 14:
15. An extrusion system comprising:
a) an extruder having an extruder outlet, the extruder configured to extrude an extrusion profile from the extruder outlet; and
b) a puller apparatus positioned downstream of the extruder outlet, the puller apparatus comprising:
i) a path through which the extrusion profile travels downstream from the extruder outlet;
ii) an upper extrusion puller member and a lower extrusion puller member defining a first portion of the path wherein at least one of the extrusion puller members is a drive extrusion puller member, the drive extrusion puller member providing forward motion to the extrusion profile travelling through the path; and
iii) a mounting arm moveably mounted to the puller apparatus, the mounting arm having a a pair of laterally spaced apart arm segments, each arm segment having a substantially central mounting location at which location the mounting arm is moveably mounted to the puller apparatus, the mounting arm having a first portion on one side of the substantially central mounting locations and a second portion on an opposed side of the substantially central mounting locations, the first portion is mounted to the upper extrusion puller member, the second portion having a laterally extending cross member spanning the arm segments,

wherein the mounting arm is moveable from a lowered position in which the upper extrusion puller member is positioned to engage the extrusion profile in the path and a raised position in which the upper extrusion puller member is spaced upwardly from the lowered position,
wherein the second portion of the mounting arm is unconnected to any portion of the puller apparatus other than a part of the mounting arm whereby, during operation the mounting arm is freely moveable between the lowered position and the raised position,
wherein the first portion of the mounting arm travels upwardly and forwardly as the mounting arm travels from the lowered position to the raised position, and
wherein the mounting arm is moveable from the lowered position to the raised position by applying an external force to the cross member.
