Glass separation apparatus can comprise a first vacuum port facing a first side of a glass ribbon travel path. The glass separation apparatus can further comprise a first gas knife comprising a first gas outlet facing the first side of the glass ribbon travel path. The first gas outlet can define a first sheet plane intersecting the first side of the glass ribbon travel path. The first sheet plane can be at least partially located upstream from the first vacuum port. In further embodiments, methods of separating a glass ribbon can comprise intersecting a first gas sheet with the first major surface of the glass ribbon at a first intersection axis extending across a travel direction and located upstream from a separation path. The methods can further comprise separating the glass ribbon along the separation path and shielding glass particles generated during the separating with the first gas sheet.
