DEVICE FOR THE TRANSPORT OF LEAVES TO BE SURVIVED ESPECIALLY PAPER SHEETS

摘要

A file of successive sheets is delivered to a converting station by a faster first conveyor, and a stream of partially overlapping sheets is removed by a slower second conveyor. Partial overlapping between the leading sections of successive sheets in the file and the trailing sections of the respective preceding sheets in the stream is due to the difference between the speeds of the two conveyors. A deflector assembly at the converting station ensures that the leading sections of successive sheets of the file can predictably overlap with the trailing sections of the immediately preceding sections of the stream by causing the trailing sections to move out of the way of oncoming leading sections and/or vice versa. To this end, the deflector assembly applies to the trailing sections and/or to the leading sections a force which can be varied in dependency upon one or more parameters such as the speed of the first and/or second conveyor; the flexibility, specific weight, moisture content and/or size of the sheets; the temperature at the converting station and/or in the path of the file; the dimensions of the leading and/or trailing sections of the sheets; and/or others.
