Abstract: A hopper for a cigarette making machine for use with a continuous tobacco feed comprises substantially parallel downwardly-extending walls defining a channel for receipt through the upper end thereof of a continuous supply of tobacco forming a relatively thick carpet of tobacco. A roller at the lower end of the channel is arranged to convey the carpet of tobacco from the channel at a variable speed towards a spiked conveyor. The spikes have a tobacco-carrying capacity greater than the tobacco feed rate existing when the roller rotates at its maximum speed. The conveyor consists of a spiked drum which rotates in a direction such as to carry tobacco upwards from the relatively thick carpet conveyed to it by the roller. The conveyor also includes a spiked roller which is arranged to remove the tobacco from the spiked drum and to cause the tobacco to move generally downwards. A pair of substantially parallel downwardly-extending walls defines a second channel which is arranged to receive tobacco from the spiked drum. The distance between these walls of the second channel is small enough to form a relatively thin carpet of tobacco in the second channel.
