    Abstract: An improved film cutter for severing sheets of soft stretch film which is drawn in a plane into a wrapping machine from a continuous source of such film comprises a first elongated knife blade extending laterally across the plane defined by the film and having a serrated cutting edge facing the film. A knife bracket extends laterally across the opposite side of the film plane and forms a channel such that the first knife blade may be moved or inserted into the channel to sever the film. The knife bracket comprises an elongated first member, with a knife mounting bar secured thereto and spaced therefrom to define the channel. The knife mounting bar includes a flange extending away from the channel and toward the film oriented at an acute angle to the knife mounting bar such that the extended edge of the flange forms a thin film contacting edge of the channel. A second knife blade is secured parallel to the knife mounting bar and spaced therefrom, with the second knife blade having a serrated cutting edge facing the film and extending in the channel to a point short of the film contacting edge of the channel.

    Abstract: The present invention relates to a method and apparatus for producing a smooth edge blank from stock material. A blanking die is carried by the movable die shoe and a closely cooperating blanking punch is secured on the fixed die shoe. Spring biassed means is displaceably provided within the blanking die to apply pressure on a sheet of stock located on the punch only over the area to be blanked out from said sheet of stock. A piercing punch may also be provided and extends coaxially through the blanking die and a bore extending through the blanking punch provides a piercing die. The spring biassed means for applying pressure to clamp the stock only over the area to be blanked is a shedder displaceably disposed within the bore of the blanking die. A stripper encircling the blanking punch is provided for removing scrap stock upon completion of the blanking step and a spacer means is disposed to space the blanking die and the stripper apart by a distance exceeding the thickness of the stock.

    Abstract translation: 本发明涉及一种从原料生产平滑边缘坯料的方法和装置。 冲裁模具由可动模具承载，并且紧密配合的冲裁冲头固定在固定模具鞋上。 弹簧偏压装置可移动地设置在冲切模具内，以将压力施加在位于冲头上的坯料上，仅在从所述坯料上消失的区域上。 还可以提供穿孔冲头并且同轴地延伸通过冲裁模具，并且延伸穿过冲切冲头的孔提供穿孔模具。 用于施加压力以将库存仅夹在待冲切的区域上的弹簧偏压装置是可置换地设置在冲切模具的孔内的脱落器。 提供了围绕冲裁冲头的剥离器，用于在冲切步骤完成时移除废料，并且设置间隔件装置以使冲裁模和剥离器间隔距离超过坯料的厚度。

    Abstract: A metal cutting band saw including a vertically pivoting endless blade tensioned and guided for selective raising and lowering relative to a workpiece clamping vise. A single control lever is provided for effecting the vertical movement of the blade or saw band with the frame mounting the blade selectively closing and opening a drive motor switch. The workpiece clamping vise is adjustable so as to clamp workpieces of different sizes therein and, when adjusted, automatically opens and closes in response to a vertical movement of the frame mounted saw blade. The saw blade guides are adjustably mounted and include bearing means whereby a true vertical orientation of the blade and an elimination of any tendency for the blade to roll is achievable. Guide means is provided on the free end of the blade frame for ensuring a true vertical movement thereof and adjustments cooperate with the opposed blade mounting wheels for a proper alignment thereof.
