Abstract: An ink pad device with ink reservoir for coating a stamping device with ink comprising ink reservoir, cap, housing, high-absorbency ink pad, low-absorbency ink pad and ink pad cover. The present invention incorporates an ink reservoir to an ink pad so that the ink pad device may be used indefinitely by refilling the ink reservoir with ink, thereby avoiding the predominant situation wherein the ink pad device is discarded when the ink in the ink pad is depleted and the ink pad subsequently dries up. The ink in the ink reservoir is absorbed by the high-absorbency ink pad located in the bottom of the housing and in turn the low-absorbency ink pad placed on top of the high-absorbency ink pad absorbs the ink in the high-absorbency ink pad, thereby preventing a given stamping device from acquiring excessive amount of ink from the ink pad device.

Afterwards, the objects are separated from each other, the porous sheet being pulled upwards. Then, the objects, to which adhesive agent has been applied, are brought together again so as to be glued to each other.

Abstract: An oil distribution system for a heat and pressure fuser includes a metering assembly which gravity feeds oil along an inclined channel to a plurality of reservoirs. The metering assembly has a length which approximates the length of the fuser roll surface to be oiled. Oil is introduced into the inclined channel and fills each of the reservoirs.

The reservoirs are spaced in such a way that uniform dispensation of oil is provided. The primary wick receives the oil and feeds it to a fuser roll. A secondary wick helps to control the uniformity of the oil on the fuser roll.
