ABSTRACT:
An apparatus device for ripping woven textile goods has a table having an upper surface, near and far longitudinal edges, and a transversely elongated slot extending between the edges and having transversely spaced near and far slot ends, the goods normally lying on the table extending across the slot. At least one outer rail extends transversely along the slot and at least one inner rail riding on the outer rail is displaceable therealong between a far end position projecting past the far slot end and a near end position projecting past the near slot end. A carriage displaceable substantially the full length of the inner rail is also displaceable between a far end position past the far slot end and a near end position past the near slot end. A ripping element on the carriage can be displaced on displacement of the carriage and inner rail between their end positions fully across the goods lying on the table across the slot to tear them weftwise.
