Abstract: A device for washing and removing liquid on a gauze conveyor for conveying products, the gauze conveyor having an upper side for carrying products and being provided with link portions and having a gauze pattern. The device having means for removing liquid on the upper side of the gauze conveyor and being formed by a hollow, rotatable roll which is provided with rows of separate projecting teeth, said rows extending axially on the roll, the teeth fitting into the gauze pattern and the link portions being enclosable by the teeth. The roll has holes between the teeth which holes extend into the cavity of the roll.

Abstract: Method for adjusting the shape of at least one side of the circumference of a strip of flexible material to the shape of a reference side concerned. The method comprises the steps of determining the shape of the at least one side of the strip, comparing the shape as determined of the at least one side with the shape of the reference side, and adjusting the shape as determined of the at least one side to the shape of the reference side, depending on the outcome of the comparison. Belt strip feeding apparatus for feeding a belt strip on a rotating building drum. The feeding apparatus is provided with a supply reel for containing belt material, with means for unwinding belt material from the supply reel, with conveying means for conveying the unwound belt material to the building drum, with cutting means placed above the roller conveyor for cutting the belt material into a belt strip.

Abstract: Assembly of a loading means with a horizontal loading surface and a strip stacker for depositing an unvulcanized rubber strip on the loading surface. The strip stacker containing a depositing mechanism with a depositing end and with a pair of conveyor belts for transporting a rubber strip vertically between the conveying belts to the depositing end and a feed conveyor for transporting a rubber strip to the depositing mechanism in a transport direction. The feed conveyor has an input end and an output end. The loading means is provided with means for variably adjusting the distance between the depositing end and the loading surface. The depositing mechanism is provided with means for moving recriprocably in one direction the depositing end with regard to the loading surface. The strip stacker is provided with means for moving the output end of the feed conveyor substantially transverse to the transport direction.

Abstract: A device for removing liquid on a gauze conveyor for conveying products, the gauze conveyor having an upper side for carrying products and being provided with link portions and having a gauze pattern. The device having means for removing liquid on the upper side of the gauze conveyor by extraction said means being placed directly under the gauze conveyor and being formed by a hollow, rotatable roll which is provided with rows of separate projecting teeth, said rows extending axially on the roll, the teeth fitting into the gauze pattern and the link portions being enclosable by the teeth. The roll has holes between the teeth which holes extend into the cavity of the roll.

Abstract: Mechanism for supporting and retaining the beads when building at least a portion of a pneumatic tire on a building drum, said mechanism comprising radially expandable and retractable means for laterally supporting at least a part of each bead, wherein a large number of rocker arms is arranged in a ring shape about the center line of the building drum, and means serve to shift and swivel all of these rocker arms simultaneously to an expanded position and to retract them again, said swivelling action of each rocker arm being performed in an imaginary plane extending radially through the center line of the drum and said shifting action including a component directed along the center line of the building drum.

Abstract: A cutting device for cutting strips of unvulcanized rubber to proper lengths for building a pneumatic tire, in particular a radial tire, said device comprising at least one conveyor and a cutting apparatus working crosswise with respect to said conveyor for cutting a strip of unvulcanized rubber, wherein said apparatus for cutting said strip comprises means to vibrate a knife longitudinally to and fro with high frequency e.g. ultrasonic frequency and means to move the knife vibrating longitudinally to and fro along a track crosswise with respect to said strip.

Abstract: Apparatus for assessing the weld in a belt layer for a radial pneumatic tire in which the belt layer has been disposed onto a rotary drum, comprising an apparatus for directing at least one laser beam towards the drum and the belt layer, said laser beam being directed obliquely with respect to the perpendicular on the belt layer and the drum, and a camera for viewing the position of the projection of the laser beam on the drum and the belt layer.

Abstract: A drum to build and form a belted tire, having a central support element, the central portion of which consists of radially slidable segments, and two bead retainers arranged at both sides of said support element, the spacing of said bead retainers being axially adjustable symmetrically with respect to the support element, the bead retainers having, at their circumference, radially expandable, integrally formed rings arranged to be brought into engagement with the tire in an air-tight manner, wherein the support element has an integrally formed rigid cases between the central portion and the bead retainers, the rigid cases being fixedly connected to the side of the bead retainers facing the central portion, the contact face of each rigid case facing the central portion being bevelled, the segments of the central portion which are arranged between the two cases engage the bevelled contact faces of the cases, are retained by springs and are similarly bevelled at the place of contact with the cases, whereby when
