Abstract: The present invention relates to a trimming apparatus operable in an auto mode or a manual mode. The trimming apparatus include a cutter frame, a transmission belt, a motor, a clamping element, a switch and a mode-switching unit. By adjusting the mode-switching unit to control clamping element to clamp or release the transmission belt, the trimming apparatus 100 is operated in either the auto mode or the manual mode.

Abstract: The present invention relates to a shredder having a thickness triggering device. During the shredding operation, the trembling of the article is minimized or eliminated by using the shredder. The shredder includes a sustaining mechanism and a driving assembly. Since the sustaining mechanism is sustained against the shredding article, the amplitude of the trembling article is largely reduced. As a consequence, the influence of the shredding article on the thickness triggering device is reduced so as to prevent interruption of the shredder.

Abstract: A gear assembly of a laminating apparatus includes a fixed gear device and an adjustable gear device connected between a motor and the fixed gear. The adjustable gear device includes a transmission shaft driven by the motor to rotate, a movable gear sleeved on and slidable along the axial direction of the transmission shaft, and an urging device coupled to the movable gear. The movable gear engages with a fixed gear in an object laminating mode but disengages from the fixed gear in an object releasing mode. For disengaging the movable gear from the fixed gear, an external force is exerted to force the movable gear to move toward and sustain against the urging device, and for restoring the engagement of the movable gear with the fixed gear, the external force is released to have the urging device push the moveable gear back to the engaging position.

Abstract: A soft sided briefcase is disclosed which has typical compartments and further includes external pockets with secure flap closures. The pockets are affixed to the side of the briefcase, and the flap closures are suitably hinged to a portion of the pockets. Sections of the pockets as well as areas of the flaps include cooperating steel plate members and permanent magnets, or both having permanent magnets, to provide access faster than would be possible via conventional zipper closures and is reasonably secure in providing protective closure for internal contents.

Abstract: The present invention provides an expansion system for luggage comprising an upper frame, a lower frame, an expandable section attached between the upper and lower frames, and expansion mechanisms. Each expansion mechanism comprises an upper member attached to the upper frame, a lower member attached to the lower frame and two arms, wherein each arm is pivotally connected to the upper member at one end and is pivotally and slideably connected to the lower member at the other end.

Abstract: The surfaces of a metal pull tab which is hingedly secured to a metal bracket on a zipper slider and/or the surface of the bracket which engages the pull tab is covered by a non-metallic relatively soft coating which prevents wear caused by metal-to-metal contact between the pull tab and the bracket and reduces noise caused by free-swinging contact between the pull tab and the zipper or slider to which it is attached.

Abstract: A laminating apparatus includes a roller, an electro-heating shaft, a power transmitting and resilient member and a power transmitting and securing member. The roller is in contact with a thin film, moves through the thin film to heat and laminate the thin film to a sheet material. The electro-heating shaft is wrapped by the roller, transforms electric energy into thermal energy to heat the thin film, and drives rotation of the roller to move through the thin film. The power transmitting and resilient member is in contact with an axial end surface of the electro-heating shaft in an axial direction of the electro-heating shaft for transmitting electricity from a power source to the electro-heating shaft. The power transmitting and securing member is coupled to the electro-heating shaft for compressing the power transmitting and resilient member therebetween, thereby continuously transmitting the electricity from the power source to the electro-heating shaft via the power transmitting and securing member.

Abstract: A hot laminating apparatus for laminating a sheet material and thin films to be hot laminated has heat shield to keep the working temperature thereof. It includes a transmitting and heating roller disposed at one side of a transmission passage of the hot laminating apparatus for heating a thin film in contact therewith and transmitting the sheet material with the thin films through the transmission passage. The hot laminating apparatus further includes a heat shield disposed around the transmitting and heating roller, and covered with a heat-reflective material on an inner surface thereof for reflecting the dissipated thermal energy back to the transmitting and heating roller.

Abstract: A roller heating system for a laminating machine comprises a first rolling shaft and a second rolling shaft, wherein the first rolling shaft and the second rolling shaft are parallel with each other, and a heating mechanism is mounted on the respective surface of the two rolling shafts. Then, a heat conduction layer wraps up the respective surface of the above-mentioned rolling shafts as well as the heating mechanisms. When the lamination proceeds, the heat mechanisms firstly heat the heat conduction layers to a working temperature and at the same time, the first and second rolling shafts respectively rotate in a predetermined direction, and then an article covered with laminating plastic films is fed into the roller heating system. The heat conduction layers heat the laminating plastic films to melt the fusion gum of the inner surfaces of the laminating plastic films, and subsequently the laminating plastic films are forced by the compression of the first and second rolling shafts to adhere to the article.

Abstract: A hot laminating apparatus has a single-sided transmitting and heating roller. A heating plate is used instead of a transmitting and heating roller at the opposite side of the transmission passage in order to heat the thin film in contact therewith and cooperate with the single-sided transmitting and heating roller to transmit the thin films to be laminated. The heating plate is efficient in heating the thin film and generally less expensive than the transmitting and heating roller.
