Implementción de un prototipo neumático para el prensado de cuero para el laboratorio de curtición de pieles de la Facultad de Ciencias Pecuarias

Abstract

In the tanning of skin of FOR of ESPOC H, it was performed the implementation of a pneumatic prototype for the leather pressing, in order to the prototype performance validation, it was used a sampling technic whose population were the number of skins that are processed in the laboratory and it was determine 16 kind of skins applying an descriptive statistics of the results. The pneumatic prototype was made ir function to the leather dimensions to treat, the laboratory capacities and security condition in the procedures. It was designed the pneumatic prototype taking in consideration the modification over the leather functional conditions to reach the ironing, quality requirements and the stage automation. It was developed the procedure manual of leather pressing machine in which is completed the right protocol in order to the leather ironing, procedure security conditions and activities to perform in order to programed management of machine. It was valid the machine procedure to press throughout production proofs of leather, verifying the influence of pressing conditions (temperature, pressure and time) It was evidenced that to apply a mayor time, pressure and temperature it was reacned an increase In the degree of compaction and moisture loss on leather, which promotes the increased density, resistance to physical effort and fullness of leather, however a decrease in softness and flexibility was noted in them
