The gluing unit is provided with: a glue tank (); a glue applicator roller () that applies the glue on the back (r) of a text block (P); a motor () that rotates the glue applicator roller; a wiper () that adjusts the amount of glue adhering to the glue applicator roller; a wiper drive mechanism that brings the wiper closer to or away from the glue applicator roller; and a control unit () that controls the wiper drive mechanism.

Glue application unit for perfect binding machine

The glue application unit comprises side glue application members which have a pair of scrapers () and can engage with the back margins (s) of the book block (P). The scrapers consist of elastic rod-like bodies () and scraping portions () provided at leading ends of the bodies. The scrapers obliquely extending in a direction of movement of the book block from the outside of the path of the downwardly protruding portion of the book block into the path in such a way that the scrapers contact each other in an inverted V shaped configuration. The scraping portions engage with the back margins of the book block by the elastic biasing of the bodies while the downwardly protruding portion of the book block passes between the scrapers.

A machine for attachment of a cover to a book block comprises a press plate elevating mechanism for elevating a press plate, a nip plate drive mechanism for sliding nip platesand, and a controllercontrolling the press plate elevating mechanism and the nip plate drive mechanism. The press plateelevates from the lower standby position to an upper press position. The press platepresses the coverto the book blockat the upper press position. The coveris attached to the book blockby pressing the coverto the lower end surface of the book block. The press plateis elevated from the intermediate position to the upper press position, staying at the intermediate position during a waiting time for adjustment. The press plateelevates from the intermediate position to the upper press position.

A sheet feeding machine comprises a housing, a feed section for feeding a plurality of sheetsin a feed direction, and a detecting sectionhaving detectorfor detecting informationprinted on the sheet. The detecting sectioncomprises a support framefor supporting the detector, a guide railmounted on the support frameand extending for guiding the detector, and a guide mechanismarranged between the housingand the support framefor guiding the support frame. The support framecan be accommodated in the housingwhen detecting the informationof the sheet. The support framecan be drawn out of the housingwhen moving the detectoralong the guide rail

Sheet feeding machine

An ultrasonic transducer incorporated into an ultrasonic inspection apparatus for examining existence of defect in a sample dipped in water comprises a transducer main part having an oscillator which projects an ultrasonic wave to the sample, receives the reflected wave from the sample and outputs the received reflected wave as an echo signal, a transmitter substrate producing a drive pulse for emitting the ultrasonic wave to the oscillator, a receiver substrate for amplifying the echo signal, a housing for containing therein both substrates electrically connected, and connecting member for electrically connecting between a signal input/output terminal and the side of the oscillator in the transducer main part, wherein, when a maximum operational frequency of the ultrasonic wave emitted from the oscillator is referred to as fmax [MHz], the connecting member is set at a length of 100/fmax [cm] or less. Even if the sample to be examined is small, a desirable defect inspection can be achieved at an excellent examination accuracy.
