图1表示一个传送片子的空气传送带铝模型,把空气注入压缩室4,并强迫通过槽8上的各孔6。模型的塑料窄条10紧密地压进槽8,塑料条上有许多小的空气喷口12,空气喷口12直接与槽8上的孔6对准,以便空气也能通过喷口12推动片子
Fig. 1 shows an air transfer belt aluminum model for transferring the sheet, injecting air into the compression chamber 4 and forcing it through the holes 6 in the groove 8. Fig. The plastic strip 10 of the model is pressed tightly into the trough 8 and the plastic strip has a number of small air jets 12 aligned directly with the holes 6 in the slots 8 so that air can also push the film through the jets 12
