    摘要: A self-propelled wrapping machine movable around a load to wrap the load with a plastic film in a wrapping cycle, comprising a self-propelled carriage; a upright fixed to the carriage and slidably supporting an unwinding unit provided at least with a reel of film; a first gripping unit that is supported by the carriage, and is movable and arranged to hold and unwind an initial flap of film from the unwinding unit in an initial step of the wrapping cycle; and a second gripping unit that is supported by the carriage, and is movable and arranged to position and release an anchoring element on the initial flap of film in the initial step of the wrapping cycle so as to fix the initial flap of film to a supporting plane and to grasp and lift the anchoring element from the supporting plane so as to disengage it from the initial flap of film after at least one turn of the self-propelled wrapping machine around the load wrapping the load with the film supplied by the unwinding unit.

    摘要: A mandrel for supporting a roll of flexible web material has a brake mounted thereto that can be selectively activated to apply a braking force to rotation of the roll of flexible material about the mandrel. The brake includes an inflatable bladder and a shoe, such that when the bladder is inflated the shoe is pushed into engagement with the core of the roll of flexible material. The mandrel is particularly well suited for use with a packaging machine in which a sheet of flexible material is indexed form the supply roll. Before the completion of an indexing cycle, the bladder may be inflated such that further advancement of the sheet of flexible material or rotation of the supply roll is countered and inhibited. This braking of the supply roll advantageously introduces tension to the sheet of flexible material without the use of a dancer roll arrangement.

    摘要: A unit for positioning a sheet (1) of film (2) to cover the tops of product groups (3) comprises: a second roll (12) of film (2); a first carriage (13) that is slidably mounted on guide rails (14) running along an upper horizontal plane and is driven in both directions along the wrapping area (10) by motorized movement means (15); the first carriage (13) is equipped with a first gripper unit (16) designed to grip the free end of the film (2) and to unwind the film (2) for a predetermined length; film (2) cutting means (17) located in the vicinity of the second roll (12) and designed to separate the length of film thus unwound from the rest of the film (2); a second carriage (18) slidably mounted on the guide rails (14) in the vicinity of the cutting means (17); a second gripper unit (19) mounted on the second carriage (18), acting on the film (2) in such a way as to hold the sheet (1) at a second retention point when the cutting means (17) are activated; means (20) for coupling the second carriage (18) to the motorized movement means (15) in such a way that, when engaged, the two carriages (13, 18) can move together as one in order to position the sheet (1) centrally on the top surface of the product group (3).

    摘要: A packaging apparatus has a lift mechanism to lower and raise a tool, such as a formation box that functions to form cavities in a web of flexible material. The lift mechanism has a series of arms, supported by belt driven carriages, which move in tandem to raise and lower the formation box. The arms are arranged into two sets such that when the arms within each set are moved closer to one another, the formation box is raised, and when the arms within each set are moved away from one another, the formation box is lowered. The common driving of all arms by a belt allows the indexing of the formation box to be well controlled.
