1901D Modular Belt Flight
CSTRANS supplies 1901D flights for the 1901 modular belt family. Upright flights provide a moving barrier across the carrying surface to support product positioning along the run.

Leave Clearance Around the Flight
Check its full path through the conveyor ends and return supports, including the space above and beside it.
A Moving Barrier Across the Carrying Run
The 1901D flight projects above the belt to engage the product behind its base. Successive flights divide the carrying run into spaces for the conveyed load. Their height and spacing should suit the product and the loading method.
POM and PP flight materials are listed. The flight arrangement must be reviewed with the base belt and conveyor, since the raised parts travel through a larger envelope than a plain carrying surface.

Specifications
| Parameter | Specification |
|---|---|
| Model | Specification: 1901D |
| Component | Specification: Flight |
| Flight materials | Specification: POM / PP |
| Associated belt pitch | Specification: 19.05 mm / 0.75 in |
| Nominal width options | Specification: 76.2 / 152.4 / 228.6 / 304.8 / 381 / 457.2 / 533.4 / 609.6 / 685.8 / 762 mm |
| Standard nominal width | Specification: W = 76.2 × N mm |
| Nonstandard nominal width | Specification: W = 76.2 × N + 19 × n mm |
N is a positive integer; n is a nonnegative integer. Specify flight height, spacing and side offset against the drawing.
Set the Pocket and Travel Envelope
Use the drawing's H, K and M references to identify height, spacing and side position. Check the product length against the space between flights and the way products enter that space.
Support Product Positioning on an Incline
On an inclined section, a flight can provide a physical barrier behind the conveyed load. The selected height and spacing must suit the product shape, incline and loading pattern.
Flights also change loading and discharge timing. A product arriving across a flight can be lifted or displaced, so coordinate the feed position with the pocket spacing. Check the final release onto the receiving conveyor with the same care.

Specify a 1901D Flight Layout
Send belt width, flight height and spacing, side offset and quantity. Include incline angle, product dimensions and a side view of the return and discharge.
