A fit-holding groove is formed by notching the outer periphery of a door element to be fitted to close a container body. A sealing element interposed between the container body and door element is composed of an endless portion to be fitted into the fit-holding groove, a protruding part projected from the peripheral corner of the endless portion, obliquely and outwardly with respect to the open front of the container body, forming a substantially acute angle between itself and the contact surface of the open front of the container body and a pair of fitting ribs projectively formed on the obverse surface of the endless portion so as to be fitted in contact with the compartmentalized inner wall of the fit-holding portion.

A ring-shaped low load seal attached into a ring-shaped dovetail groove having an opening portion, a first side wall face, a second side wall face, and a bottom wall face. This seal has a trileaf cross-sectional configuration composed of a first arc portion, a second arc portion, a protruding portion, and a concave portion disposed between the first arc portion and the second arc portion.

A safety device detects when a worker's hand enters a hazardous region between rollers of a kneading machine, and stops rotation of the rolls to prevent an accident. Each time the rollers are stopped, the orientation of photoelectric sensors is switched from the vicinity of the gap between the two rollers to a test reflection member, and the quantity of received light is compared to a predetermined value, to prevent workers form starting work without knowing a fault or accident has happened. More specifically, a bar electrode of an electrostatic capacitance sensor is disposed above and near the gap between the two rollers, for detecting a physical quantity that is changed by entry of a worker's hand. When the electrostatic capacitance detected by the sensor exceeds a predetermined value, a judging circuit supplies a control signal to stop a driving unit that operates the kneading machine. Heat ray sensors or photoelectric sensors may be used as alternatives to electrostatic sensors. As an additional feature, case housing light projectors and photoelectric sensors are rotatably disposed above and near the gap between the two rollers, and a test reflector is disposed on the side of the case. When the rollers are stopped, a light receiving object switching circuit rotates the case and a test circuit tests the light receiving states of the photoelectric sensors.

Safety device for a kneading machine using rolls

An apparatus for inspecting an O ring which detects surface flaws of O rings by successively sending O rings by a conveyor, projecting light and inputting pictures of O rings, and processing the pictures. The apparatus is provided with a vibrating screening machine for separating products and flashes removed from the products and feeding the products of O rings to the conveyor.
