The chute is where many cap feeding problems appear.
Even a good feeder can perform badly if the cap chute is too long, steep, shallow, narrow or poorly matched to the cap. The chute has to preserve orientation and maintain the right queue pressure at the capper.
Cap feeder chutes are influenced by closure shape, required presentation, discharge height, capper position and guarding. Incorrect chute design can lead to shingling, jams, cap bounce or missed pick-up.
Chute design should be considered as part of the full system, not left until the feeder is already built.
