A method for processing and storing plates (L, L'), particularly glass plates, which comprises: - a processing step, in which at least one plate to be processed is cut on a horizontal processing surface of a cutting line, - a storage step, in which at least one offcut plate (L'), which is the result of the cutting of said plate to be processed, is stored in a storage structure, - a step of recovery of the offcut plate (L') in which an offcut plate (L') is taken from the storage structure and repositioned on said processing surface in order to be further processed, characterized in that said storage step comprises the substeps of: s1. transferring said at least one offcut plate (L') from said processing surface onto a tilting machine, while keeping said offcut plate (L') in a substantially horizontal position, s2. tilting said offcut plate (L'), by way of said tilting machine, to a substantially vertical position, s3. moving said offcut plate (L') from said tilting machine, bringing it above said processing surface and keeping it in a substantially vertical position, by way of a handling arm, s4. depositing said offcut plate (L') in a storage structure, arranged above said processing surface, in a substantially vertical position; and in that said step of recovery the offcut plate (L') comprises the substeps of: r1. taking from said storage structure, by way of said handling arm, at least one previously stored offcut plate (L') and, while keeping it in a substantially vertical position, depositing it on said tilting machine in a substantially vertical position, r2. tilting said offcut plate (L'), by way of said tilting machine, to a substantially horizontal position, r3. transferring said offcut plate (L') from said tilting machine onto said processing surface, while keeping said offcut plate (L') in a substantially horizontal position. - a processing step, in which at least one plate to be processed is cut on a horizontal processing surface of a cutting line, - a storage step, in which at least one offcut plate (L'), which is the result of the cutting of said plate to be processed, is stored in a storage structure, - a step of recovery of the offcut plate (L') in which an offcut plate (L') is taken from the storage structure and repositioned on said processing surface in order to be further processed, characterized in that said storage step comprises the substeps of: s1. transferring said at least one offcut plate (L') from said processing surface onto a tilting machine, while keeping said offcut plate (L') in a substantially horizontal position, s2. tilting said offcut plate (L'), by way of said tilting machine, to a substantially vertical position, s3. moving said offcut plate (L') from said tilting machine, bringing it above said processing surface and keeping it in a substantially vertical position, by way of a handling arm, s4. depositing said offcut plate (L') in a storage structure, arranged above said processing surface, in a substantially vertical position; and in that said step of recovery the offcut plate (L') comprises the substeps of: r1. taking from said storage structure, by way of said handling arm, at least one previously stored offcut plate (L') and, while keeping it in a substantially vertical position, depositing it on said tilting machine in a substantially vertical position, r2. tilting said offcut plate (L'), by way of said tilting machine, to a substantially horizontal position, r3. transferring said offcut plate (L') from said tilting machine onto said processing surface, while keeping said offcut plate (L') in a substantially horizontal position. s1. transferring said at least one offcut plate (L') from said processing surface onto a tilting machine, while keeping said offcut plate (L') in a substantially horizontal position, s2. tilting said offcut plate (L'), by way of said tilting machine, to a substantially vertical position, s3. moving said offcut plate (L') from said tilting machine, bringing it above said processing surface and keeping it in a substantially vertical position, by way of a handling arm, s4. depositing said offcut plate (L') in a storage structure, arranged above said processing surface, in a substantially vertical position; r1. taking from said storage structure, by way of said handling arm, at least one previously stored offcut plate (L') and, while keeping it in a substantially vertical position, depositing it on said tilting machine in a substantially vertical position, r2. tilting said offcut plate (L'), by way of said tilting machine, to a substantially horizontal position, r3. transferring said offcut plate (L') from said tilting machine onto said processing surface, while keeping said offcut plate (L') in a substantially horizontal position.
