Abstract:
A sheet retention device is provided for retaining at least one sheet. The sheet retention device comprises a sheet supporting means (56) for supporting at least a first portion of the sheet, a rotatable guiding means (50) configured to enclose a second portion of the sheet, an urging means (61) and a drive means for in operation controllably rotating the rotatable guiding means. The rotatable guiding means comprises a passageway (55) arranged through the rotatable guiding means, which passageway is configured to enclose the second portion of the sheet, the passageway having an entrance portion (55a) at one side of the rotatable guiding means and an exit portion (55b) at another side of the rotatable guiding means. The rotatable guiding means comprises an outer surface (51) and a sheet deflecting surface (53), such that in operation during at least part of a revolution of the rotatable guiding means a portion of the sheet is guided by the sheet deflecting surface into a sheet retaining position (60). The sheet retaining position is defined by the outer surface of the rotatable guiding means and the urging means. The urging means are urged against a portion of the outer surface of the rotatable guiding means.
Abstract:
본 발명은 캐스팅 테이프(casting tape)의 권선 방법에 관한 것으로서, 상세하게는 캐스팅 테이프의 최초 권선 부분이 접히지 않은 상태로 캐스팅 테이프를 보빈(bobbin)에 감을 수 있도록 한 캐스팅 테이프의 권선 방법에 관한 것이다. 이를 위하여, 본 발명은, 보빈의 둘레에 캐스팅 테이프를 감는 캐스팅 테이프의 권선 방법에 있어서, 상기 캐스팅 테이프를 절단하여 상기 보빈 상에 안착시키는 단계와, 압착 봉을 상기 보빈에 밀착하여 상기 캐스팅 테이프를 상기 보빈 상에 압착시키는 단계와, 상기 보빈을 권선 회전 방향과 반대 방향으로 회전시키는 단계와, 상기 캐스팅 테이프의 최초 권선 부분이 상기 압착 봉에 도달하면 상기 압착 봉을 상기 보빈에서 이탈시키는 단계와, 상기 보빈을 권선 회전 방향으로 회전시키는 단계를 포함하는 것을 특징으로 한다. 상기와 같이, 본 발명은 캐스팅 테이프의 최초 권선 부분이 접히지 않은 상태로 캐스팅 테이프를 보빈에 감을 수 있기 때문에, 시술자가 캐스팅 테이프의 접혀 있는 부분을 펴야 하는 불편함이 없으며 캐스팅 테이프를 마지막 부분까지 편리하게 사용할 수 있는 효과가 있다.
Abstract:
The device has a pre-centring apparatus (VZ), a drive unit (AE) and a buffer apparatus (PV). The pre-centring apparatus (VZ) accepts the printing-material web (10) from a printing-material web source and is configured in such a way that the printing-material web (10) is aligned laterally after passing through and is set into a tensioned state. The drive unit (AE) is arranged at the outlet of the pre-centring apparatus (VZ), which drive unit (AE) pulls the printing-material web (10) from the pre-centring apparatus (VZ) and drives it in the process. The buffer apparatus (PV) is arranged between the drive unit (AE) and the printing device, which buffer apparatus (PV) tensions the printing-material web (10) before it is fed to the printing device.
Abstract:
A method for flipping over a printing media, comprising: a) capturing the printing media in a nip between a driver roller and a pinch roller; b) turning the driver roller while holding at least a leading portion of the printing media against the driver roller, so that the printing media moves forward around the driver roller; c) releasing the leading portion of the printing media from the driver roller; d) changing the forward velocity of the leading portion of the printing media, while the driver roller continues to move a trailing portion of the printing media caught in the nip forward, thereby causing the paper to buckle away from the driver roller; e) releasing the trailing portion of the printing media from the nip; and f) allowing the trailing portion of the printing media to fall so that it ends up in a flipped over orientation.
Abstract:
The present invention relates to a method for winding a casting tape, and more particularly, to a method for winding a casting tape which can wind the casing tape onto a bobbin without folding the firstly wound portion of the casting tape. For this purpose, the present invention provides a method for winding the casting tape onto the circumference of the bobbin, comprising the steps of: cutting the casting tape and placing the cut tape onto the bobbin; enabling a compression rod to tightly contact the bobbin to compress the casting tape onto the bobbin; rotating the bobbin in the direction opposite the winding direction; enabling the compression rod to escape from the bobbin when the firstly wound portion of the casting tape reaches the compression rod; and rotating the bobbin in the winding direction. As described above, the method of the present invention can wind the casting tape onto the bobbin without folding the firstly wound portion of the casting tape, thus preventing the inconvenience of the operator having to unfold the folded portion of the casting tape, and enabling the casting tape to be conveniently used up until the last portion thereof.
Abstract:
A method for flipping over a printing media (102), comprising: a) capturing the printing media in a nip between a driver roller (108) and a pinch roller (110); b) turning the driver roller (108) while holding at least a leading portion of the printing media (102) against the driver roller, so that the printing media (102) moves forward around the driver roller; c) releasing the leading portion of the printing media (102) from the driver roller (108); d) changing the forward velocity of the leading portion of the printing media (102), while the driver roller (108) continues to move a trailing portion of the printing media (102) caught in the nip forward, thereby causing the paper to buckle away from the driver roller; e) releasing the trailing portion of the printing media (102) from the nip; and f) allowing the trailing portion of the printing media (102) to fall freely so that it ends up in a flipped over orientation.
