## Abstract

Plant to perform cropping and to take samples, which is suitable to crop the head and tail of a rolled product which may travel at high or very high speeds, the head and tail being discharged through an independent discharge conduit (15), the plant comprising at least one flying shears (11) at least for the shearing and correct delivery of the head and tail, the discharge conduit (15) cooperating with a flying shears (18) to take samples, at least one container (19) for the portions collected as samples being located downstream of the sampling flying shears (18).

## Claims

### Claim 1

Plant for cropping and sampling a rolled product, and for processing the rolled product at high or very high speeds, comprising: at least one first flying shears for shearing the head and tail from rolled product passing through and for correctly delivering the sheared head and tail; a discharge conduit receiving the sheared head and tail delivered from said first flying shears; a second flying shears downstream of said discharge conduit for shearing the terminal portion of the sheared head or the initial portion of the sheared tail to form sample portions of the sheared terminal or initial portion and remaining portions of the sheared head or tail, and for separately discharging said sample portions and said remaining portions; and at least one sample-portions container for collecting only the sample portions separately discharged from the second flying shears.

### Claim 2 (depends on 1)

Plant as claimed in claim 1, wherein the sample portions are terminal portion of the sheared head and the initial portion of the sheared tail.

### Claim 3 (depends on 1)

Plant as claimed in claim 1, wherein said second flying shears can also shear intermediate portions of the head and/or tail to form the sample portions.

### Claim 4 (depends on 1)

Plant as claimed in claim 1, further comprising a channel downstream of said first flying shears for receiving the rolled product, and a coiling machine downstream of said channel.

### Claim 5 (depends on 1)

Plant as claimed in claim 1, further comprising a scrap container for collecting only said remaining portions separately discharged from the second flying shears.
