摘要:
A pasting roller has brush bristles planted in a surface thereof in straight lines or spirally to form a plurality of rows at predetermined intervals on the roller surface. An adhesive sheet S is pasted to work while moving the pasting roller and the work, which is the recipient, relative to and crossing each other. In this pasting process, a rotating speed of the pasting roller is adjusted according to a surface configuration of the work to render the pressure on the adhesive sheet constant.
摘要:
The invention relates to a sealing apparatus comprising a sealing unit (1) for weld sealing packages and an electronic control unit (2) for actuating the sealing unit (1). The control unit (2) has an electronic interface (3) for supplying sealing process log data such as the applied sealing pressure, duration of the applied sealing pressure, sealing temperature, and the like in a raw data format. According to the invention, an electronic evaluation unit (4) is assigned to the electronic control unit (2) in order to convert the sealing process log data into a processed data format, and a removable, portable storage medium (5) is allocated to the evaluation unit (4) in order to store the sealing process log data.
摘要:
Films of thermoplastic material may be sealed together by application of a radio frequency field through a pair of oppositely positioned electrodes. Preferred thermoplastic materials have a low dielectric dissipation factor, and such materials include polyethylene. The sealing apparatus includes a circuit having compensation and matching circuits for providing resonant operation and minimizing the amount of reflected energy from the electrodes. Through the use of this invention effective RF sealing is produced between films of thermoplastic material having a low dielectric dissipation factor. Further the sealing apparatus preferably includes at least one electrode coated with a ceramic and a release material for providing thermal conduction to the films, thereby enhancing the sealing effectiveness of the apparatus.

There is disclosed herein an improved apparatus 30 and method for stuffing pre-inked printer ribbon from a ribbon roll 460 into a ribbon cartridge 46. The apparatus 30 includes a drive motor 322 for pulling the ribbon into the cartridge 46 and a supply motor 66 connected to a spool 32 for automatically feeding ribbon to the cartridge. Between the drive and supply motors, the ribbon passes through a splice detection means 34, around a length measuring means 36, and through a cutter mechanism 38. The length measuring means 36 includes a brake 154 for stopping motion of the ribbon. The cartridge loading apparatus 30 further includes a built-in ribbon welder mechanism 40 for adjoining the end of the pre-inked ribbon to a leader ribbon assembled into the cartridge 46 and a cartridge support means 318 adaptable to any cartridge configuration.
摘要:
A plastic pressure vessel comprises a first (1, 2) and a second part (2, 1) welded to each other. The first part (1) comprises a layer (11) of thermoplastic material having substantially continuous fibres. The second part comprises a layered structure having an first (20) and a second (22) layer of thermoplastic material having substantially continuous fibres separated by a central (21) layer comprising thermoplastic material. The layer having substantially continuous fibres (11) of the first part extends over a length (d) sandwiched in between and connected with the first (20) and second (22) layer of thermoplastic material having substantial continuous fibres of the second part. Preferably the second part is provided with a slit (24) and the first part with a fitting protrusion, preferably with a bevelled end (23).
