The upper Porm sections 20 are carried by a cross member 60. On opposite sides of the lower mold sections 21, guide plates 61 extend upward from the press frame 23. At each end of the crossbeam 60, rollers 63 and 64 supporting 3? UteRngsaxme 62 are provided. The rollers run in front and rear vertical inspection grooves 65 baw. 66 in the Mtaungsplatten 61. The cross member 60 is on both sides of the press outside of the Mtaungsplatten 61 on top of two actuation bars. 67 pivotally mounted, the gear wheels 68 ″ are actuated, which in turn are driven by a motor 69 via a gear 70 to raise and lower the cross member 60 for the purpose of opening and closing the press

A control device 75 arranged approximately on the front side between the lower standard sections 21 has two oppositely extending members 76R, 76L, one for each poxm.

As can be seen in particular ame figures 4 ®nd 5, is a approximately triangular G-ehäuae 81 with ateshmbarera .. cover 83 by means of Screws 82 attached to the platen 22. Paragraphs 84 at the top of the case near the front corners and thus aligned Ansätse 85 are below on the inside of the housing

pierced and are used to store the Püfolglieder 16R ₇ 76L. Sin on. the underside of the housing 81 symmetrically attached Ansata 86 with a bore 87 accommodates a gear pot 88 with a cover 90 extending downward through a hole 89 in the plate 22.

The Getsiebekopf 88 is "fitted with an upwardly extending hollow shaft firmly into the Bohrimg 87, lubricant" means for the transmission members in the ott & rmüe bore 91 "head of the G-ehäasea 81 out can be achieved by itself sum inside" are introduced.

Its bore in the side of the head takes on a large size Axial "=" oil sealing "93 provided insert bushing 92 in the the shaft 94 of a bevel gear 95 is rotatably mounted. The bevel gear 95 is attached to the end 96 of a shaft 97.

According to Pig & r 2 is mounted, the shaft 97 near its other end in a fixed bottom of the platen 22 holder 98 and bears on this end © in pinion 99, which, as shown in phantom in Figure 3, connected via a chain 100 to a sprocket 101 is ₉ which in turn is arranged on the inner end 102 of the hub of one of the gafanräöer .68 of the press drive. In general, for example, a ratio of 1s2 between puzzle 99 and sprocket 101, with riddle 99 being smaller than the sprocket, is satisfactory.

According to Figure 4, the sail wheel 95 is in engagement with a Bevel gear 103 «n <ä sait the Sätaen 104 at the lower end of a rotatable sleeve 105 »is the shaft 97 of the press drive

Bevel gear 103 is attached to the lower BMe 106 of a vertical shaft 107. The shaft 107 is rotatably mounted in an axial bore 108 aeE sleeve 105 and ends at the upper end in a threaded cap 109 for attachment of an upper support plate 110. At the upper end of the sleeve 105 surrounding the shaft 107, a larger bearing plate 111 is attached. Is on the upper support plate 110 by means of a? Wing nut 112 fastened the control cam 78R _$ aa of the lower support plate 111 detachably by means of a wing nut 113

Each Pühlglied 7SR ₉ 761 has an approximately horizontally protruding from the housing 81 Plihlarra 115 and is curved downwards at the inner end "116 to accommodate the upper end of a vertical bearing parts 118 = They bearing shafts 118 are rotatably mounted in the Aneätsen 84» 85 of the housing 81 .

The actuation of the cylinder 128 is carried out by a pressure medium, which is not shown, controlled by a pressure medium (not shown), controlled by a pink pink circle (not shown). This control causes the piston rod 127 to be extended after the alignment of a vulcanized tire seal B with the molding device 25 and the molding section 21 in order to put the foot members 76R, 76L attached to the shafts 118 ... into their operative position To move o ßemäss Pigur 5, the extending KoTbeastange 127 rotates the feeler 76R counterclockwise and the Ptihl member 763j clockwise ₉ until the cam follower rollers 122 and 132 the control surfaces of the control cams 7SH baw «. 78Ii feerüteen _o
