Abstract

Disclosed is a loin puller for trimming off the backfat of a loin that has been scribed from a belly. This loin puller has a frame on which is mounted a conveying system for engaging the loin and moving it towards a cutting zone. In this zone, a cutting tool is mounted for engaging the loin when it is moved by the conveying system, and for cutting the backfat to be trimmed off from the loin, with the so-cut backfat remaining attached to the belly. The cutting tool has two blades that are preferably controlled independently from each other. One of these blades is arcuate and positioned onto the frame so as to engage at least one part of the loin from a side of the loin opposite to the belly, and to cut the backfat to be trimmed from the loin. The other blade is L-shaped and positioned onto the frame so as to engage another part of the loin and cut the backfat to be trimmed thereof directly from the scribing line just below the back ribs of the loin. The two blades are long enough to ensure that all the backfat of the loin be trimmed off. Advantageously, the arcuate blade has one end pivotably attached to the frame by a joint and another opposite end attached either to the frame or the L-shaped blade. The use of such a joint gives much more flexibility of the arcuate blade and makes it much more efficient.
