Abstract
Abstract A tobacco shredding machine receives tobacco to be comminuted at such a rate that the weight of quantities delivered during successive identical unit periods of time is always the same. This enables the shredding machine to turn out shredded tobacco at a constant rate. The feeding unit which supplies tobacco to the shredding machine employs a weighing device which can weigh batches of tobacco or embodies a belt conveyor, a metering device which can operate intermittently or continuously and delivers tobacco to the weighing device, and a transporting device which transports tobacco from the weighing device to the shredding machine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
Apparatus for comminuting tobacco, comprising a cutting machine; and a feeding unit for supplying to said cutting machine tobacco at such a rate that the cutting machine receives during each of a series of successive identical periods of time tobacco quantities of identical weight so that, by cutting such quantities of identical weight during each of said identical periods of time, the output of said cutting machine remains constant, said feeding unit comprising a weighing device arranged to accumulate said quantities per period of time, metering means for supplying tobacco to said weighing device, compacting means for condensing said quantities into batches having predetermined volumes, and transporting means for conveying said batches to said cutting machine.
Claim 2
Dependent Claim
116 words
Apparatus for comminuting tobacco, comprising a cutting machine; and a feeding unit for supplying to said cutting machine tobacco at such a rate that the cutting machine receives during each of a series of successive identical periods of time tobacco quantities of identical weight so that, by cutting such quantities of identical weight during each of said identical periods of time, the output of said cutting machine remains constant, said feeding unit comprising a weighing device arranged to accumulate said quantities per period of time, metering means for supplying tobacco to said weighing device, compacting means for condensing said quantities into batches having predetermined volumes, and transporting means for conveying said batches to said cutting machine.
