摘要:
A paper input mechanism having a buffer function and a printing device using the mechanism are disclosed. The paper input mechanism (300) includes a frame (1) forming a conveying passage (P) for conveying continuous paper, and further includes a fixed passage plate (4) and a buffer plate (2) both located at a paper inputting side of the conveying passage (P), wherein the buffer plate (2) has an initial position and is pressed by the continuous paper to deviate from the initial position; the buffer plate (2) is opposite to the fixed passage plate (4) when being located at the initial position, so as to form a paper input passage (R), and the paper input passage (R) is connected with the conveying passage (P). Arrangement of the buffer plate (2) not only implements the buffer function, but also results in close fit between the buffer plate (2) and the frame (1) of the paper input mechanism (300) to create a unique paper inputting port, thereby effectively avoiding the problem that continuous paper is incorrectly installed by a user, and improving the usability of the product.

A method for producing bags (64) containing fibre material, comprises the steps of forming at least one continuous layer (16) of fibre material; separating in succession portions (23) of fibre material from the continuous layer (16) and moving them along a predetermined path; feeding each portion (23) of fibre material to respective containment and compaction elements (50) of a first transfer conveyor (48); feeding an ordered succession of bags (64) containing respective portions (23) of fibre material to respective supporting elements (70) of a second transfer conveyor (58); transferring the portions (23) of fibre material from the containment and compaction elements (50) of the first transfer conveyor (48) into respective housings (56) of a third transfer conveyor (54); transferring the portions (23) of fibre material from the housings (56) of the third transfer conveyor (54) inside respective containment bags (64) carried by supporting elements (70) of the second transfer conveyor (58); transferring the containment bags (64) housing respective portions (23) of fibre material from the respective supporting elements (70) of the second transfer conveyor (58) to a fourth transfer conveyor (74); and moving in succession the bags (64) housing respective portions (23) of fibre material to a folding unit (G) at which the bags (64) are closed.
摘要:
The invention relates to a device for cutting paper webs, comprising a substantially continuously operated area for feeding paper and a discontinuous area for transversely separating the paper web. A buffer area (15) is provided for coupling the continuous and discontinuous areas, wherein at least one box-like container (17) open at the top is provided, into which the paper web(s) (3, 3') are guided so as to be looped in a freely suspended manner. The buffer area is arranged after a longitudinal cutting apparatus (9) for producing at least two longitudinal webs (3,3'), whereby at least two webs extending separately and adjacently to one another are guided in the container or at least two containers are arranged adjacently to one another or adjacently to one another at an offset, wherein the paper webs are guided into said containers.

In a drive mechanism (8) for a device for laying, in particular an unfolded fibrous material web, in particular a paper web or a corrugated paper web (1), such as a corrugated cardboard web, in a Leporello fold, comprising a pair of opposing rollers (19, 21) that form a passage gap (23) for the fibrous material web and/or define a rotational axis around which said rollers rotate, in particular when the fibrous material web passes through the passage gap, it is provided that the at least two rollers are pivot-mounted such that the rotational axes can be pivoted about the common pendulum axis by a rotational axes roller drive that rotationally drives at least one of the two rollers for delivering the fibrous material web through the passage gap to form the Leporello stacking, and by a pivot drive that has in particular a pendulum axis (P) not coinciding with the rotational axes.
摘要:
The present invention relates to a method and equipment for the handling of web materials (200), such as essentially continuous webs of plastic films, textiles, non-wovens, or paper, or the like, or of parts or pieces of such webs. In particular execution, it relates to modifying the movment of such web materials (200), so as to allow other process steps to be performed on or with these web matterials more easily. Particular aspects relate to the creation of a cross-directional fold in the web material and the combining of web materials (200) with other materials.
摘要:
A high speed input system for an inserter machine. The system controlling a guillotine cutter (21), a cutter transport (90), and an upstream web handler transport (80) to increase throughput for mail production. The controller is programmed to control the high speed input module in accordance with a repeating cycle. The cycle time is determined as an amount of time between a first web feed request and an earliest possible time that a subsequent second web feed request can be acted upon. A cutter transport motion control profile initiates feeding of a document length of web after receiving the first feed request. The cutter motion control profile causes the cutter blade to begin descending when the cutter transport has moved the web (120) a trigger distance, calculated such that the cutter blade (21) will first make contact with the web immediately when the web has been halted by the cutter transport motion profile. A web handler transport profile moves the web the document length at velocities and accelerations less than the velocities and accelerations of the cutter transport. At the end of the cycle, the web handler transport causes the web to be transported at a nominal velocity selected to maintain an appropriate amount of the web loop in the web handler. Within the web handler a control loop expands and contracts as the downstream cutter transport stops and starts as the cutter blade cuts the web in each cycle.
