Abstract
Abstract In a reel handling process, particularly in connection with an equipment for the dyeing of such reels, orderly arranged reels are withdrawn and mechanically slipped onto the rods of dyeing baskets; after the dyeing the reeis are mechanically drawn from the dyeing baskets and placed on a basket for centrifugation. A handling system comprises a loading and or unloading apparatus (76) for loading and/or unloading the reels on rods of a dyeing basket (130) and for placing separating discs between the reels; and if it is the case an applying apparatus for clamping devices.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
155 words
A process for handling yarn reels (R) particularly in connection with loading thereof into a dyeing cabinet, comprising transferring reels (R) to a dyeing basket (130) and slipping thereof on basket rods (AR), placing separating discs (DS) between each reel and the next, characterized in that gripping of each reel for the transfer takes place engaging the inside of the reel, and in that the drawing of a reel for transfer to the basket takes place substantially at the same time to the placing of a separating disc (DS) on a reel (R) previously positioned on a rod (AR) and the placing of the reel on the rod takes place at the same time of the lifting of a separating disc to be subsequently placed on said reel, and furthermore in that it includes angular rotation of the basket (130) by predetermined angles when a certain number of reels on a loading rod is reached.
Claim 2
Dependent Claim
155 words
A process for handling yarn reels (R) particularly in connection with loading thereof into a dyeing cabinet, comprising transferring reels (R) to a dyeing basket (130) and slipping thereof on basket rods (AR), placing separating discs (DS) between each reel and the next, characterized in that gripping of each reel for the transfer takes place engaging the inside of the reel, and in that the drawing of a reel for transfer to the basket takes place substantially at the same time to the placing of a separating disc (DS) on a reel (R) previously positioned on a rod (AR) and the placing of the reel on the rod takes place at the same time of the lifting of a separating disc to be subsequently placed on said reel, and furthermore in that it includes angular rotation of the basket (130) by predetermined angles when a certain number of reels on a loading rod is reached.
Claim 3
Dependent Claim
28 words

A system for handling articles particularly yarn reels (R) and particularly in relation to a dyeing treatment, characterized in that it includes a transfer apparatus (76) to transfer yarn reels.
Claim 6
Dependent Claim
43 words
A system according to claim 3, characterized in that said transfer apparatus (76) includes at least a pliers member (114, 300) made of spreadable rod of a size suitable to be introduced between a rod of the dyeing basket and a reel thereon.
Claim 7
Dependent Claim
33 words
A system according to claim 3, characterized in that said transfer apparatus (76) includes a movable crosspiece (110) carrying two pliers members (114, 116) spaced apart and shiftable transversely to the crosspiece movement.
Claim 8
Dependent Claim
102 words
A system according to claim 3, characterized in that said transfer apparatus (76) includes a gripping member (114, 300) for reels having at least two jaws (312) movable between a closed position, where they do not engage the inner wall of a reel core, and an open position where they engage it, each jaw having a tang attachment means and an operating means, and a gripping portion (318); and also a stop or abutment means (320, 320a) extended from said jaw, said gripping portion having an enlarged shape on each jaw so as to form a total bulb shape at closed jaws.
Claim 9
Dependent Claim
32 words
