Machine for cutting cardboard tubes, comprising a cutting unit (CU) with a carriage (7) on which is mounted a blade (6) and a support element (4, 5, 8) for supporting a cardboard tube (1) intended to be transversely cut by the blade (6), wherein the said support element (4, 5, 8) allows the tube (1) to slide along a predetermined direction (A) parallel to its axis longitudinal (x) and to rotate about the same axis, and wherein said carriage (7) is adapted to move bidirectionally the blade (6) parallel to the longitudinal axis (x) of the tube (1). The support element (4, 5, 8) has, where said cutting unit (CU) is arranged, a part (5) movable from and towards the blade (6) to maintain the tube (1) spaced from the latter and, respectively, for approaching the tube to the same blade (6) during a cutting phase.

Method for applying glue on tubular cores for the production of logs of paper material comprising the step of supplying in sequence more tubular cores (1) along a predetermined advancing direction (A) and the step of applying on each of said cores (1) a predetermined amount of glue, and the glue is applied on the tubular cores (1) from the above. While advancing along said direction (A) and without interrupting their run, the tubular cores (1) intercept for a predetermined time the glue (EG) released by a predetermined number of nozzles (114); and during said time interval the glue (EG) is both on the nozzles (114) and the tubular cores (1) given the absence of any element interposed between the nozzles and the tubular cores.
摘要:
Process for the production of paper rolls, comprising a step of producing logs (L) of paper material by winding a predetermined amount of paper web (W) about a respective longitudinal axis, a step of transverse cutting of the logs (L) to obtain rolls (RO) of predetermined length, and an intermediate step of transporting the logs (L) from a rewinder (R) that produces the logs (L) toward a cutting-off machine (CM) that cuts them transversely. Said intermediate transporting step involves the handling of the logs (L) along a path comprising a lateral deviation, so that, as they advance, the logs (L) are subjected to said lateral deviation.
摘要:
A method for storing cardboard tubes (2) in a storing unit according to the present invention comprising the following steps: providing a storage unit with an input section for the tubes (2), a storage section (AC) comprising a plurality of storing planes (13), an output section for the tubes (2), transfer means (3) for transferring the tubes (2) from the input section to the storage section, and discharge means for conveying the tubes (2) from the storing section to the output section; providing a plurality of cardboard tubes (2) in the input section (E) of said storage unit; transferring the tubes (2) from the input section of the storage unit to the storage section; storing a plurality of tubes (2) in said storage section (AC); transferring the tubes (2) from said storage section (AC) to said output section. The step of transferring the tubes (2) from said input section to said storage section involves more tubes (2) simultaneously, whereby a plurality of tubes (2) are transferred from said input section simultaneously on a plurality of storing planes (13) of the storage section (AC).
摘要:
Device for controlling the sharpening state of a blade (2) having a cutting edge (20) delimited by two sides (21, 22) converging towards a plane (X) that contains the cutting edge itself. The device comprises two control surfaces each of which is in contact with a corresponding side (21, 22) of said cutting edge (20) and is connected with at least one transducer (R1, R2, R4), which produces an electrical displacement signal (S1, S2; S4) proportional to a displacement of the control surface with respect to said plane (X). The control surfaces are the outer surfaces of two rotating feeler probes (30, 31).
摘要:
Device for sharpening blades of cutting-off machines, comprising two grinding wheels (1) each positioned on a corresponding side of a cutting edge (20) of a blade (2) of a cutting machine. The device comprises means adapted for controlling the symmetry of said cutting edge (20), with a sensor (3) placed at a predetermined distance from a corresponding side of the cutting edge (20. The sensor (3) is adapted to detect possible differences (d) between the lengths (n, p) of the two sides of the cutting edge (20). The sensor (3) is connected to a programmable unit (4) that processes the said difference (d) possibly detected by the sensor (3).
摘要:
Retractable step comprising a tread which slides bi-directionally along a guide with corresponding sliding means, the tread being driven by motor means comprising an electric motor to which it is connected by means of a mechanical transmission, so as to be disposed in a first retracted configuration in which the tread is in a corresponding housing body and in a second extracted configuration in which the tread protrudes from said housing body, the guide being arranged on two sides of said housing body. Said sliding means comprise a body provided by said guide and having a profile that is complementary coupable with a sliding pad (23) integral with the tread, the contact between said body and the sliding pad (23) occurring on a discontinuous contact surface, said contact surface having a predetermined number of discontinuities through which possible accumulations of dirt formed between the same sliding pad (23) and the body can flow out.
