FLOATING HEAD ASSEMBLY FOR A PULTRUSION PROCESS

摘要

A head assembly for a pultrusion process having a centre line and being substantially fixed to a supporting surface and for putruding pultrudable material, the head assembly comprising a floating adjustable assembly having a front, rear, top, and bottom, and having disposed therewith a pultrusion die having a centre line disposed at the intersection of both the vertical and horizontal planes, said die having a front or entrance, and a rear or exit, the pultrudable material passing from the entrance of the die to the exit of the die and thus substantially forming the finished shape of the pultrudable material, the centre line for acceptable pultrudable material extending within predetermined limits along the centre line of the process as the material passes from the exit of the die, the centre line of the exit of the die always remaining stationary and disposed proximate the centre line of the process, the die being fastened in position with respect to the head assembly by at least one mounting member also having a front, rear, top and bottom, the head assembly having disposed therwith proximate the rear thereof proximate the exit of the putrusion die a fixed frame portion fixed in position with respect to the supporting surface, the at least one mounting member and hence the pultrusion die being moveably affixed (for example pivotable) with respect to the fixed frame portion, the head assembly having disposed therewith at least one adjustment actuator to provide for adjustment of the head assembly and therefore the entrance of the die with respect to the exit of the die, the at least one adjustment actuator being fixed to the supporting surface and affixed with respect to the at least one mounting member and thereby providing the adjustment of the front of the head assembly, wherein should the centre line of the form of the pultrudable material exiting the die be out of line with the pedetermined limits from the centre line of the process the adjustment actuator will upon the operation thereof adjust the position of the entrance of the die with respect to the centre line of the process and the exit of the die by effecting the movement of the front of the at least one mounting member and therefore the front of the die with respect to the fixed frame portion sufficiently until the centre line of the pultrudable material is again substantially in line with and within acceptable limits from the centre line of the process and the exit from the die.
