| Résumé : |
One of the many ways of increasing efeciency in the meat packing industry has been the substitution of hide pulling machines for the old method of hand flaying with knives. Several distinctly different types of machines and procedures have been developed for bide removal. It was estimated in 1972 that 75 percent of United States hides were removed with pullers. This has resulted in a general improvement in hide quality due to a significant decrease in hutcher cuts. However, this procedure, especially with the newer "clown puller," can exert so much force that it could cause considerable grain-crack damage at various hide locations. This damage ("grain break") was described and illustrated in a pamphlet issued by the Tanners' Hide Bureau in 1972. Tancous also pointed out that, while hide pulling machines greatly reduced the damage from flay cuts, they may introduce new damage from grain cracks. Proper handling and adjustment of machines have been shown to minimize this problem.
Some packers and hide dealers feel that hides identified as Hereford hy their hair color may be the most troublesome in this respect. If so, then perhaps the weakness caused by the vertical liber defect, which occurs most frequently in these Hereford-type hides, may be responsible. A packer with this thought in mind offered to cooperate with us to obtain further information. |
