摘要： A film forming apparatus includes a die device which extrudes a molten resin in a tube shape to form a film and a controller which controls the die device. The die device includes an inner peripheral member which defines an inner periphery of an annular discharge port, an outer peripheral member which surrounds the inner peripheral member and defines an outer periphery of the discharge port, and an adjustment portion which applies a load to at least one of the inner peripheral member and the outer peripheral member to elastically deform the at least one of the inner peripheral member and the outer peripheral member and change a radial width of the discharge port. The controller controls a thickness of the film with the load applied by the adjustment portion.

摘要： A parison head for discharging a parison for producing capillaries, tubes or pipes, includes a sleeve-shaped housing into which the melt is fed, and which surrounds a core on all sides with a spacing, the core being firmly clamped in the housing, and also a likewise sleeve-shaped die, which likewise surrounds the core on all sides with a spacing, wherein the housing and the die surround the core in such a way that there is a closed flow channel between the housing and the core and between the die and the core, and at the end of the flow channel a peripheral closed outlet gap is formed by the die and the core, wherein there is between the housing and the die a low-cost, quickly exchangeable, trifunctional component, which securely seals off the flow channel between the housing and the die, and with which the angle between the housing and the die and also the length of the head can be changed, while retaining the flow resistance in the region of the trifunctional component and while retaining a flow channel that is free from dead spots, and so in this way the cross section of the flow channel gap at the end of the flow channel is variable.

摘要： An extrusion nozzle for making tubular preforms has a mandrel extending along a vertical axis, an annular and stationary nozzle body spacedly radially surrounding the mandrel, and a holding ring having an upper end axially slidable in the nozzle body, braced axially downwardly against the nozzle body, and having a lower end spaced radially inward from shiftable limitedly radially relative to the nozzle body. A nozzle ring has an upper end axially slidable in the holding ring, is braced axially downwardly against the nozzle body, and has a radially deflectable lower end forming an annular extrusion gap with the mandrel. A first positioner engages the lower end of nozzle ring and is operable to radially deflect this lower end. A second positioner engages radially with the lower end of the holding ring or with the nozzle ring for radially deflecting same.
