A flat film and sheet-forming melt extrusion die includes a unitary die body 1 shown in Fig. 1 which is an end view in elevation and partially in section of the die, at the feed end thereof. Fig. 2 is an end view in elevation and partially in section of the die, at the end opposite the feed end, with the lower die lip member removed. Fig. 3 is a section taken along line 3-3 of Fig. 1. The die body 1 has a feed inlet 32 and a distributor channel 11 in communication with feed inlet 32 and with die orifice 2. The die at its end opposite feed inlet 32 is provided with end plate 30. The die has a removable lower die lip member 7 which extends into die body 1 and rests along its base, indicated by line 9, on the lower internal surface of die body 1 and abuts the perpendicular wall of die body 1 along line 10. It is held in contact with die body 1 by means of bolts 8. Rear bevelled wall of lip member 7 and that portion of land (l) of lip member 7, which extends from'the apex of wall 12 to the entrance of passageway 17, in conjunction with walls 15 and 16 of die body 1, define distributor channel 11, the cross-sectional area of which progressively decreases from the feed inlet 32 of the die to an extremity of the channel. Passageway 17, defined between land (l) of lower die lip member 7 and land (l<SP>1</SP>) of upper die lip member 3, is in communication with channel 11 and forms at its tip, die orifice 2. Upper die lip member 3 is attached to die body 1 by bolt assemblies 4 which are "push-pull" bolts by means of which the distance between die lip members 3 and 7 can be altered and the width of the slotshaped die orifice thereby adjusted. In the preferred embodiment shown in Fig. 4 the upper die lip member 44 is an integral part of die body 40 and extends under and is spaced from rigid member 43 which is also an integral part of die body 40. Members 44 and 43 are connected at intervals along their extremities by " push-pull " bolt assemblies 46 by means of which die lip member 44 is flexed at point 45 and the width of slot-shaped die orifice 41 thereby adjusted. The streamlined shape of the feed ducts in the body of the die prevent stagnation and resultant degradation of the hot thermoplastic material to be extruded and the die has the requisite strength to withstand without distortion the forces developed during the extrusion of highly viscous smelts of thermoplastics. The die can be quickly and easily cleaned.

Abstract: 1,156,938. Making eyelets; stamping; metal strip feeds; punching. TEXTRON Inc. 6 Oct., 1966 [15 Oct., 1965], No. 44646/66. Headings B3A, B3Q and B3W. A press for performing on metal blanks consecutive operations, e.g. drawing, piercing, shearing, embossing and threading, comprises a frame 11, two adjacent sets of plungers and dies 15, 16 in the frame and means for transferring the blanks between the work-stations. Blanks may be fed to the press or, as shown, blanked from strip-stock 100 at a station at each end of the press. The plungers of one set operate 180 degrees out of phase with those of the other set, and the blanks proceed in steps towards adjacent inner stations where they are ejected through passages 99 by punches 98 on the inner plungers. The two tool sets may produce different types of articles simultaneously. The press has an upper cam-shaft 60 for effecting downward and return strokes of the plungers 21, 31, and a low cam-shaft 65 for operating ejector pins 61 beneath the dies 20, 30, the shafts being interconnected by a shaft 71 and driven, through belts 54, 59, by an electromotor 50. Lift cams on the cam-shaft 60 act through abutments (84), Fig. 2 (not shown) and coupling rods (85) to raise the plungers 21, 31. Strip feed.-The strip passes transversely through the press at the blanking station of the set of plungers 21 where blanks are punched from one margin of the strip. It then passes through a guide 120 on the top of the frame 11 and again through the press at the other blanking station, where blanks are punched from the other margin of the strip. An idler roll 101a and a feed roll 101b engage the strip at the left-side of the press, the roll 101b being driven intermittently, through a one-way coupling 104, by a rod 105 connected to a crank disc 106 which is driven (Fig. 2) from the crankshaft 65. A similar roll-feed 102 exists on the opposite side of the press. Blanks transferring.-A slide 90, Fig. 4, having end pockets 97 for co-operation with the blanking stations and spring fingers 96 for transferring the blanks, is connected to a further slide 91 which is reciprocated by a cam 93 driven by the shaft 71. Operation.-The blanking punch on one side of the press shears a blank from the strip and forces it into a recess 97 of the feed-slide 90. Movement of the slide transfers the blank to the second station and moves the other recess 97 beneath the blanking punch at the opposite side of the press. The blanks are pushed from the slide by punches on the plungers and stripped from the punches, as they rise, by strippers (not shown) so as to enter the transfer spring-fingers 96. The forming plungers rise in two steps between which they are stationary, Figs. 5a-5c (not shown). Scrap produced in the forming operations is removed through tubes (not shown).
