ABSTRACT:
An enclosure inserting and sealing machine of the type in which, envelopes received in an envelope hopper are delivered one by one sequentially with each envelope being centered by an envelope centering mechanism in the widthwise direction of the envelope relative to the envelope delivering line. The envelope delivered is opened at the position of an envelope opening mechanism with the front and rear sides of the envelope being respectively sucked by suction caps of the envelope opening mechanism. Enclosures such as a paper, a letter and the like are inserted into the opened flap of the envelope. At least the suction cap of the rear side of the envelope is formed in a pair in the widthwise direction of the envelope. A suction position centering mechanism is provided to drive the pair of suction caps in the widthwise direction of the envelope thereby centering the suction caps. A linkage mechanism is provided to link and drive the suction position mechanism with the envelope centering mechanism.
