Abstract: The present invention aims to provide a tread pickup device which can pick up a tread on a truck reliably without manpower. The device comprises a plurality of short first forks for scooping up a front edge of the tread placed on the truck and holding the tread, long second forks which are arranged adjacent to the first forks and inserted throughout the total width of the tread, and a mechanism for raising and moving the first and second forks together with the tread.

Abstract: An object of the present invention is to provide a tread centering device which automatically detects the position of tread center and holds it in a straight form even when the center of tread is not positioned in a straight form. The device mainly comprises a plurality of detectors for detecting a groove for centering the tread, a holding plate which is inserted into the detected groove, and a mechanism which moves said holding plate transversely to align said groove in a straight form.

Abstract: An apparatus joins opposite ends of a tread on a rotary drum in a tire making machine. Besides the rotary drum, the apparatus includes a conveyor having two lateral endless loops and a guide in the form of rollers interposed between the loops. The conveyor is disposed upstream of the rotary drum. Clamping mechanisms are provided to clamp the respective sides of the tread at a rear end thereof to the endless loops of the conveyor, respectively. A tread placed on the endless loops of the conveyor is maintained in relative position by the guide. The actual length of the tread on the conveyor is measured. The front end of the tread is adhered to the rotary drum and the opposite sides of the tread at the rear end thereof are clamped to the conveyor. The conveyor and drum are then driven at appropriate speeds based on the length of the tread to cause the ends thereof to be joined on the drum. Movable grippers can be provided to stretch the rear end of the tread at the sides thereof into abutment with the front end.

Abstract: A vermin exterminating element comprising a culture carrier having culture medium components containing vermin infectious microorganisms and/or the spores of the vermin infectious microorganisms cultivated therein, and a vermin exterminating method using the same.

Abstract: A cutting device for use in cutting a cylindrical material around a mandrel into annular bodies of the desired width. This device has a first moving table to move in the axial direction of the mandrel, a second moving table to move on the first moving table in the radial direction of the mandrel, a cutter support carrying a first cutter adjustable in position in the radial direction of the mandrel and/or a second cutter adjustable in the axial direction of the mandrel, and a control unit with a device for detecting the position of each moving table, a device for receiving output signals from the detecting device and comparing the position with position data set beforehand and a driving circuit to move each moving table according to output signals from the comparing device.

Abstract: For the purpose of pressurizing and holding the pressure in a pressurizing hydraulic cylinder is a hydraulic vulcanizing press, a pneumatic booster (more particularly, a pneumatically operated hydraulic pressure booster) for supplying a desired hydraulic pressure to the hydraulic cylinder is provided in a hydraulic circuit on a pressurizing actuation side of the pressurizing hydraulic cylinder. In addition, in the pneumatic input circuit for the pneumatic booster is provided a switching device for switching a pressurized air fed to the pneumatic booster between a high pressure air for boosting a hydraulic pressure to a desired hydraulic pressure and a low pressure air for holding the desired hydraulic pressure after the desired hydraulic pressure has been attained.
