Abstract: A transporter apparatus for products includes a first conveyor, provided with seats for receiving said products and provided to move said products in a first advance direction, a compaction unit, positioned downstream of the first conveyor and a second conveyor positioned downstream of said compaction unit. The compacting unit includes a support surface on which the products coming from the first conveyor are deposited, and a movement member provided to move the products placed on the support surface towards each other in a second advance direction, so as to form compact columns of products substantially parallel to the second advance direction.

Abstract: In a method and a device for clearing yarn, properties of the yarn are acquired and used to determine a yarn defect density profile. Yarn defects to be removed are defined by means of an adjustable clearing limit which is based on the density profile. In order to provide an optimum adjustment as frequently as possible, the clearing limit is automatically adjusted on the basis of the acquired properties in a control loop.
