Burr and brace combbrace comb:

are sections of beeswax comb built on top bars or on bottom bars so bees can walk from one box to another.With incorrect bee space, combs may be secured with extra (brace) comb. Sometimes the cells are used to rear (drone) brood or store honey.

see burr comb
only if the comb interferes with frame removal or is "in the way". xcessive, compulsive removal (constantly scraping the top bars each time the hive is opened for example) can lead to defensive bees or cooling of brood nest (due to time necessry to remove).
If the comb is removed do not discard on ground as may lead to pests like skunks; gather the removed pieces to use to make beeswax products.
