Abstract
A streamer trap assembly for collecting streamers from a flow of polymer pellets includes a housing comprising an inlet, an outlet, and an opening bounded by a sealing surface; and a streamer trap positioned in the housing through the opening. The streamer trap comprises a screen sized to collect the streamers at the screen and to allow the polymer pellets to pass through the screen, a guide positioned to guide the flow of polymer pellets from the inlet to the screen and from the screen to the outlet, and a cover adapted to engage the sealing surface and cover the opening.

A streamer trap assembly for collecting streamers from a flow of polymer pellets, comprising:
- a housing comprising an inlet, an outlet, and an opening bounded by a sealing surface;
- and
- a streamer trap positioned in the housing through the opening, the streamer trap comprising a screen sized to collect the streamers at the screen and to allow the polymer pellets to pass through the screen, a guide positioned to guide the flow of polymer pellets from the inlet to the screen and from the screen to the outlet, and a cover adapted to engage the sealing surface and cover the opening.
A method of collecting streamers from a flow of polymer pellets, comprising:
- providing a housing comprising an inlet, an outlet, and an opening bounded by a sealing surface;
- positioning a streamer trap in the housing through the opening, the streamer trap comprising a screen sized to collect the streamers at the screen and to allow the polymer pellets to pass through the screen, a guide positioned to guide the flow of polymer pellets from the inlet to the screen and from the screen to the outlet, and a cover adapted to engage the sealing surface and cover the opening;
- connecting the inlet to a supply of polymer pellets;
- and
- applying a vacuum to the outlet such that the polymer pellets proceed in the inlet, through the screen, and out the outlet, and such that the streamers are collected at the screen.
